Top 10 networking stories of 2025 | Computer Weekly
There are few certainties in life: death, taxes and massively increased workloads on infrastructures through the unstoppable rise of AI.
And enterprises and connectivity providers know only too well that AI has fuelled an unprecedented surge in network demand. Keeping pace with the next wave of AI growth will require new long-haul networks to enable the rapid scaling of capacity needs in both existing and emerging enterprise setups – especially within datacentres.
The emergence and widespread adoption of agentic AI-enabled applications is reshaping datacentre requirements, prompting a rapid evolution in networking solutions. AI is driving these advancements, with a dual opportunity for network innovation and operational transformation.
Research earlier in 2025 found that core fibre investment is key to future AI growth, but four-fifths of firms delay builds because of network infrastructure constraints. In addition, global network connectivity provider Zayo predicted AI-driven datacentre capacity to grow 2-6X over the next five years while optical comms technology provider Ciena reported that AI capacity doubling every six months, with hundreds of fibres connected to datacentres being lit up.
Looking at the networks of the future, in October 2025 Cisco noted that two major forces are starting to reshape the landscape: AI agents, which raise the bar for scale, security and governance; and AI infrastructure debt, the early warning signs of hidden bottlenecks that threaten to erode long-term value.
Assessing in April 2025 how to solve these issues, leading research firm Omdia observed that to drive the continued growth of the global AI economy, networks will need to evolve significantly to deliver enhanced capabilities. New, advanced optical networks, it said, were necessary to meet advanced application and service requirements and address surging capacity needs within tight capex targets.
As well as supporting business agility to match bandwidth supply to service utilisation, these new nets – such as all photonic networks – also offer with lower power consumption per bit to meet sustainability goals and reduce energy costs.
And, perhaps most importantly, the benefits of AI in networking can’t be realised fully without considering networking for AI.
Here are Computer Weekly’s top 10 networking stories of 2025.
Just as AI offers a substantial increase in business efficiency and effectiveness, it also places challenges on the network, necessitating increased network and operational innovation. With such dynamics in mind, Nokia is expanding and enhancing its datacentre networking portfolio to meet the increasing performance and scalability demands of connecting AI workloads.
Furthermore, the comms tech company believes that it is able to do this while taking advantage of AI to drive efficiency and reliability into operations.
Datacentres, the cloud and graphics processing units (GPUs) dominate much of the tech sustainability conversation currently due to their vast energy needs. However, it’s the network infrastructure – including routing, interconnects and protocols – that is becoming the real bottleneck as AI workloads increase, due to heat output, cost and energy usage.
AI workloads put a considerable amount of pressure on networks as they are very different from traditional and predictable consumer and cloud traffic, such as streaming and web browsing. AI workloads such as large model training require high-bandwidth, persistent east-to-west traffic. This has led to a key question: can European infrastructure companies scale AI operations sustainably?
Building on its enterprise network architecture, Cisco has embarked on a plan to modernise its campus, branch and industrial networks for the AI era with systems designed to simplify operations across campus and branch deployments such as network configuration
Cisco believes the new products can simplify operations, scale for evolving business needs and enhance security – all critical for unlocking the full potential of enterprise.
The upgrades follow the launch of the IT and networking giant’s AI-ready secure network architecture for enterprises earlier in 2025. They are fundamentally designed to deliver automated deployment and security across highly distributed networks in minutes instead of months, meeting the high-bandwidth, ultra-low latency and intelligent traffic management demands of distributed AI workloads that are increasingly moving to the enterprise edge.
Research has found that “pacesetter” companies are significantly more likely to move network AI pilots into production, and 50% more likely to report measurable value from AI.
The Cisco AI readiness index 2025 revealed that while the AI genie is out of the bottle for organisations for all sizes, only 13% of businesses are fully prepared for it, with those ready as much as four times more likely to move pilots into production and 50% more likely to see measurable value.
Cisco added that the combination of foresight and foundation is delivering real, tangible results at a time when AI agents and AI infrastructure debt were starting to reshape the tech landscape.
As businesses integrate AI into more applications, demand for high-speed, low-latency, secure networks has surged, but a study from IDC has revealed that legacy infrastructure is no longer sufficient to support the scale and complexity of current, never mind future, AI workloads, and emphasises that network modernisation is crucial to ensuring AI success.
The study highlighted how networks were seen as the critical foundation empowering AI-driven growth. More than 78% of companies regarded networking capabilities as either important or very important when selecting providers for GenAI infrastructure, underscoring the need for networks that can handle and secure ever-scaling AI workloads while running complex AI training, inference and storage clusters with ease.
Research from RtBrick has warned that network operators are at risk of being “overwhelmed” by the demands of AI and streaming services on bandwidth in the next five years.
The carrier routing software provider’s study identified issues regarding not just technology but also people and processes. Consumer expectations were rising faster than the networks designed to meet them and despite significant investment in AI, operators admitted they can’t fully optimise networks without access to more real-time data and network modernisation delayed through staff issues.
There are few industries these days that are not influenced by AI. Networking is very much one of them. It is barely conceivable that any network of any reasonable size – from an office local area network or home router to a global telecoms infrastructure – could not “just” be improved by AI.
In other words, the implementation of AI results in operational efficiencies, increased reliability and user benefits. But as we know, nothing in life is simple, and to guarantee such gains, AI can’t be “just” switched on.
A progress report from metro and long-haul data connectivity firm Lumen Technologies has shown a quickening in pace in its network expansion to meet massively increasing workloads, including new fibre miles, added network capacity and coast-to-coast US build.
Altogether, Lumen said it has delivered “significant” progress in its mission to build the backbone for the AI economy, delivering the capacity upgrades and high-speed connectivity enhancements needed so that enterprises can power their AI workloads. It said that it was preparing to deliver the bandwidth required to handle large volumes of data processing, creating what the firm believes is the required high-performance pipeline for AI workloads.
Network giant Cisco has unveiled simplification of its network operations and claims to be in a position to deliver exponential performance with next-generation devices, all while fusing security into the network and making new business workflows possible.
As it announced the platform, the company quoted findings from its IT networking leader survey, which stressed how a major infrastructure shift was underway and that AI could either double the strain or solve it.
Specifically, the research found that 97% of businesses believe they need to upgrade their networks to make AI and IoT initiatives successful. Faced with these challenges, IT teams needed a new approach to scale operations, reduce downtime, and unlock new levels of efficiency and innovation. Cisco warned that there would only be two types of company in the future: those that are really adept with their use of AI, and those that really struggle.
Even though very few businesses around the world are resisting the allure of artificial intelligence (AI), research commissioned by Expereo has revealed a number of major roadblocks to UK AI plans, such as poor infrastructure, resistance from employees, and unreasonable demands, while two-fifths of UK CIOs have warned of unrealistic board expectations of AI.
Despite some of the worrying findings revealed, the research also painted a positive picture for the promise of AI, but only if businesses can overcome existing challenges. Some 88% of UK business leaders surveyed regarded AI as becoming important to fulfilling business priorities in the next 12 months.

I’ve Been Waiting Months for This Gorgeous Laptop to Drop in Price. It Finally Happened
After a long time of resisting significant price drops, the Asus Zenbook S 16 has finally dropped down to $1,000, which is $500 off its retail price.
It’s normal for laptops to dip in price toward the end of their lifespan, close to when an update comes out. But the Asus Zenbook S 16 has held on. To be fair, it’s an extremely high-end Windows laptop, one of the prettiest to come out last year. It’s sleek, portable, and has a striking design. It even gets fantastic battery life, on par with a MacBook. Speaking of MacBooks, this Zenbook is the laptop I saw tech journalists traveling with more than anything else. Given how much tech they review, that’s quite an endorsement.
But the S 16 has always been hard for me to recommend when the cheapest model available was $1,500. I was always on the lookout for a more significant price cut, but it never dropped more than a couple hundred bucks. And even though it always came with 24 GB of RAM and a terabyte of storage, the price was a hard pill to swallow. Well, the day has finally come. It’s now down to $1,000 over at Best Buy as part of the store’s Presidents’ Day sale. That’s an incredible price for this much laptop.
The previously mentioned memory and storage still apply here, along with the 2880 x 1800 OLED display with a 120-Hz refresh rate. This laptop basically has every high-end feature you could imagine, but one of my favorite aspects is the ports. Despite the thin profile, the S 16 keeps all the legacy ports you might want, including HDMI, USB-A, and even a full-size SD card slot.
There is also a smaller, 14-inch model, but its discount is not as strong as the 16-inch model. It comes in at $1,300 right now, which is still a solid price for this configuration.
I should say that Asus has an update in the works for 2026 with the latest Intel chips, but it’s only coming to the 14-inch model. I won’t lie: Based on my testing, these CPUs will make a significant difference in performance—especially on the graphics front. But I have a feeling Asus will be selling this device for an even higher price for much longer, especially with the recent development around memory shortage.
While the Zenbook S 16 is certainly the best deal at Best Buy for its Presidents’ Day sale, I would also recommend the Asus Zephyrus G14, which is also $500 off. This configuration comes with a powerful RTX 5070 Ti graphics card and is one of our favorite gaming laptops.

‘Uncanny Valley’: ICE’s Secret Expansion Plans, Palantir Workers’ Ethical Concerns, and AI Assistants
Brian Barrett: They’ve got 80 billion or so to spend 75 billion of that I think they have to spend in the next four years. So yeah, they’re going to keep expanding. And when you think of how much of an impact 3000 agents officers had in Minneapolis alone, that’s like an eighth of the, they can repeat some version of that in a lot of different spots.
Leah Feiger: And I’ve been fielding, honestly, shout out to the many local reporters around the country who’ve been contacting me in the last day or so, just to ask questions about the locations that we named that are near them or in their states or cities. And the thing to me that keeps coming up is that in addition to new buildings, they’re getting put into preexisting government buildings, preexisting leases, or that that appears to be the plan. And then we’ve also found that a bunch of these ICE offices are being located near plans for giant immigration detention warehouses, and we’re looking at offices being set up, say 20 minutes, an hour and 20 minutes away for these. Yeah. So we’re looking at different, the triangulation of this around you have to have your lawyers, your agents, have a place to get their orders and put their computers and do in some ways very mundane things that are required of an operation like this one.
Brian Barrett: Well, Leah, that’s a good point. I think when people hear ICE offices or when I do just instinctively, I think of ICE as guys with guns and masks and all that, but that’s not exactly what we’re saying here. Do you mind talking through what these offices seem to be queued up to be used for and by whom? Because ICE is not just the masked guys with bad tattoos.
Leah Feiger: Yes, absolutely. So what we reported in this story as well was some of the specific parts of ICE that actually reached out to GSA and asked them to expedite the process of getting new leases, et cetera, included in that, for example, where representatives from Ola, Ola is ICE’s office of the principal legal advisor. So that’s the lawyers, those are the ICE lawyers that are working with the courts and arguing back or deportation orders saying yes, no, et cetera, signing the documents, putting everything in front of judges. This is a really important part of this entire operation that we’re not talking about a ton. There’s a lot of focus on the DOJ. There’s a lot of focus. There was an excellent article this week in Politico talking about all of these federal judges that are really, really upset that DHS and ICE are ignoring their requests for immigrants to not be detained anymore.
The missing level of that is the lawyers that are part of this that are representing ICE to the US government here, and that’s ola. So they’ve reached out to GSA extensively as we report to get these leasing locations, specifically with the OLA legal request. I just want to get across how big this is. How massive is this ICE repeatedly outlined its expansion to cities around the us And this one piece of memorandum that we got from Ola stated that ICE will be expanding its legal operations into Birmingham, Alabama, Fort Lauderdale, Fort Myers, Jacksonville, and Tampa, Des Moines, Iowa, Boise, Idaho, Louisville, Kentucky, Baton Rouge, Louisiana, grand Rapids, Michigan, St. Louis, Missouri, rally, North Carolina, long Island, New York, Columbus, Ohio, Oklahoma City, Oklahoma, Pittsburgh, Pennsylvania, Charleston and Columbia, South Carolina, Nashville, Tennessee, Richmond, Virginia, Spokane, Washington and Cord Delaine, Idaho and Milwaukee, Wisconsin. We have other locations as well throughout the rest of the article, but those are the requests from OLA.

Waymo Asks the DC Public to Pressure Their City Officials
Waymo needs some help, according to an email message the self-driving developer sent to residents of Washington, DC, on Thursday.
For more than a year, Waymo has been pushing city officials to pass new regulations allowing its robotaxis to operate in the district. So far, self-driving cars can test in the city with humans behind the wheel, but cannot operate in driver-free mode. The Alphabet subsidiary—and its lobbyists—have asked local lawmakers, including Mayor Muriel Bower and members of the city council, to create new rules allowing the tech to go truly driverless on its public roads. The company has previously said it will begin offering driverless rides in DC this year.
But Waymo’s efforts to sway officials have stalled, so the company is now asking residents to apply some pressure. “We are nearly ready to provide public Waymo rides to everyone in DC,” says an email sent to those who have signed up for Waymo’s DC service. “However, despite significant support, District leadership has not yet provided the necessary approvals for us to launch.”
The email directs recipients to contact DC officials via a form letter that says, in part: “Over the past year, I have observed Waymo vehicles operating throughout our local areas, and I am thrilled about the potential advantages this service could provide, including enhanced accessibility and a decline in traffic-related incidents.” The communication urges DC residents to edit the letter to “use your own words,” because personalized messages “have a higher impact.” Only DC residents or those with DC addresses can participate, Waymo says.
In a written statement, Waymo spokesperson Ethan Teicher says, “We’ll be ready to serve Washingtonians this year, and urge the Mayor, the District Department of Transportation, and the City Council to act.” The company says that 1,500 people contacted district leaders through its email in the first 90 minutes after it was sent.
Generally, self-driving vehicle developers have only launched service in places where regulations clearly outline how the tech might hit the roads. Other US cities with Waymo service, including ones in California, Florida, and Texas, already had those rules in place before the company entered their markets. But as Waymo’s ambitions have grown larger, it has begun to target large blue-state cities where autonomous vehicle tech doesn’t yet have a “driver’s license.” Earlier this month, the company said it would begin testing in Boston, where city lawmakers pushed last year for an ordinance that would ban self-driving taxis from operating without a human behind the wheel. Waymo has said that it needs Massachusetts lawmakers to “legalize fully autonomous vehicles” before it can launch service in Boston.
Eventually, self-driving-vehicle developers hope that the US Congress will pass a law allowing the broader testing and operation of their tech across the US. On Tuesday, a House committee advanced a bill that would direct the federal government to create safety standards for autonomous vehicles, and prevent states from passing their own laws prohibiting the sale or use of the tech, or from requiring companies to submit information on crashes.
Waymo’s new DC pressure campaign echoes the ones launched by transportation disrupters, including ride-hailing giant Uber and bike- and scooter-share company Bird, nearly a decade ago. Like self-driving tech developers, those companies wanted to launch their new services in places where the rules didn’t align with their business ambitions. Ultimately, Uber and Lyft generally succeeded in getting laws passed in US statehouses allowing their services to operate on public roads—and preventing cities from creating their own laws.
Today, Waymo operates in six US metro areas—Atlanta, Austin, Los Angeles, Miami, Phoenix, and the San Francisco Bay Area—and plans to launch in more than 10 this year. Three other companies, including Nuro and Amazon-owned Zoox, have permits to test self-driving tech in Washington, DC.
