‘Soaring’ AI demand accelerates Lumen’s multibillion-dollar network expansion | Computer Weekly


Lumen Technologies has released a status report on its infrastructure build-out during 2025, claiming milestones on its mission to build 47 million intercity fibre miles.

Altogether, Lumen said construction was underway coast-to-coast, and that it has delivered “significant” progress in its mission to build the backbone for the artificial intelligence (AI) economy. It added that it was moving forward with a multibillion-dollar build, with plans to add 34 million intercity fibre miles by the end of 2028, as part of the 47 million intercity fibre mile target. The company said it has already delivered network capacity upgrades and high-speed connectivity enhancements in 2025 to build the network infrastructure enterprises need to power their AI workloads.

“This isn’t incremental: we’re positioning Lumen as the trusted network for AI, ensuring our customers have the network scale, speed and reliability to confidently innovate and grow without constraints,” said Kye Prigg, executive vice-president of enterprise operations at Lumen Technologies.

Highlighting specific milestones, the company said that in terms of new fibre deployed by the end of August 2025, it put down more than 2.2 million new intercity fibre miles (2,500+ route miles). This is projected to reach 16.6 million total intercity fibre miles by the end of the year. Lumen noted that it is utilising next-generation fibre optic cable from Corning to fit two times more fibre into existing conduits.

Construction efforts for signal boosters are now underway at 176 in-line amplifier (ILA) sites. Lumen observed that ILA shelters built on these sites are designed to serve as giant signal boosters along the network, with as much as triple the power density compared with traditional ILA shelters, and be updated, renewed and scaled for the future

The company has also expanded Conduit Access, completing indefeasible right of use conduit deployments across 55 additional routes expanding its ability to add and control fibre on these routes by securing long-term rights to underground pathways.

In terms of network capacity, Lumen said that by August 2025, it added 5.9+ Pbps of total capacity to its network so far this year, and that it was preparing to deliver the bandwidth needed to handle large volumes of data processing. It has also extended faster speeds, earmarking more than $100m to bring high-speed connectivity up to 400Gbps across clouds, datacentres and metros, creating what the firm believes is the required high-performance pipeline for AI workloads. The Lumen 400G-enabled network now spans more than 100,000 route miles.

With diverse routes connecting more than 50 major cities, Lumen said it operates the largest ultra-low-loss intercity fibre network in North America using fibre with 25% less optical loss than competitors. This is calculated on less loss translating to less frequent need for fibre optic signal regeneration, decreasing equipment costs with the 25% figure based on a comparison to vintage 2,000 fibre (decrease from .22 db/km loss to.17 db/km).

The network is also attributed with having 60% more capacity than traditional designs so it can move data more efficiently and at greater scale. The Lumen network is also attributed with offering less than five millisecond latency at the edge, covering up to 97% of US business demand.

Another key facet highlighted in the status report was an update on the Lumen Private Connectivity Fabric. Designed for AI workloads, its aim is to help businesses unite services and drive efficiency with a self-service portal and full lifecycle automation. It allows them to purchase, deploy and remotely manage consumption-based services with the speed and agility demanded by a multi-cloud, AI-first world.

“Every mile of new fibre and capacity upgrade adds to the strength of our Private Connectivity Fabric,” said Prigg. “Lumen is doing more than expanding infrastructure, we’re laying the foundation for the AI economy.”

Zillow Has Gone Wild—for AI

Zillow Has Gone Wild—for AI


This will not be a banner year for the real estate app Zillow. “We describe the home market as bouncing along the bottom,” CEO Jeremy Wacksman said in our conversation this week. Last year was dismal for the real estate market, and he expects things to improve only marginally in 2026. (If January’s historic drop in home sales is indicative, that even is overoptimistic.) “The way to think about it is that there were 4.1 million existing homes sold last year—a normal market is 5.5 to 6 million,” Wacksman says. He hastens to add that Zillow itself is doing better than the real estate industry overall. Still, its valuation is a quarter of its high-water mark in 2021. A few hours after we spoke, Wacksman announced that Zillow’s earnings had increased last quarter. Nonetheless, Zillow’s stock price fell nearly 5 percent the next day.

Wacksman does see a bright spot—AI. Like every other company in the world, generative AI presents both an opportunity and a risk to Zillow’s business. Wacksman much prefers to dwell on the upside. “We think AI is actually an ingredient rather than a threat,” he said on the earnings call. “In the last couple years, the LLM revolution has really opened all of our eyes to what’s possible,” he tells me. Zillow is integrating AI into every aspect of its business, from the way it showcases houses to having agents automate its workflow. Wacksman marvels that with Gen AI, you can search for “homes near my kid’s new school, with a fenced-in yard, under $3,000 a month.” On the other hand, his customers might wind up making those same queries on chatbots operated by OpenAI and Google, and Wacksman must figure out how to make their next step a jump to Zillow.

In its 20-year history—Zillow celebrated the anniversary this week—the company has always used AI. Wacksman, who joined in 2009 and became CEO in 2024, notes that machine learning is the engine behind those “Zestimates” that gauge a home’s worth at any given moment. Zestimates became a viral sensation that helped make the app irresistible, and sites like Zillow Gone Wild—which is also a TV show on the HGTV network—have built a business around highlighting the most intriguing or bizarre listings.

More recently, Zillow has spent billions aggressively pursuing new technology. One ongoing effort is upleveling the presentation of homes for sale. A feature called SkyTour uses an AI technology called Gaussian Splatting to turn drone footage into a 3D rendering of the property. (I love typing the words “Gassian Splatting” and can’t believe an indie band hasn’t adopted it yet.) AI also powers a feature inside Zillow’s Showcase component called Virtual Staging, which supplies homes with furniture that doesn’t really exist. There is risky ground here: Once you abandon the authenticity of an actual photo, the question arises whether you’re actually seeing a trustworthy representation of the property. “It’s important that both buyer and seller understand the line between Virtual Staging and the reality of a photo,” says Wacksman. “A virtually staged image has to be clearly watermarked and disclosed.” He says he’s confident that licensed professionals will abide by rules, but as AI becomes dominant, “we have to evolve those rules,” he says.

Right now, Zillow estimates that only a single-digit percentage of its users take advantage of these exotic display features. Particularly disappointing is a foray called Zillow Immerse, which runs on the Apple Vision Pro. Upon rollout in February 2024, Zillow called it “the future of home tours.” Note that it doesn’t claim to be the near-future. “That platform hasn’t yet come to broad consumer prominence,” says Wacksman of Apple’s underperforming innovation. “I do think that VR and AR are going to come.”

Zillow is on more solid ground using AI to make its own workforce more productive. “It’s helping us do our job better,” says Wacksman, who adds that programmers are churning out more code, customer support tasks have been automated, and design teams have shortened timelines for implementing new products. As a result, he says, Zillow has been able to keep its headcount “relatively flat.” (Zillow did cut some jobs recently, but Wacksman says that involved “a handful of folks that were not meeting a performance bar.”)

Do Waterproof Sneakers Keep the Slosh In or Out? Let WIRED Explain

Do Waterproof Sneakers Keep the Slosh In or Out? Let WIRED Explain


Running with wet feet, in wet socks, in wet shoes is the perfect recipe for blisters. It’s also a fast track to low morale. Nothing dampens spirits quicker than soaked socks. On ultra runs, I always carry spares. And when faced with wet, or even snowy, mid-winter miles, the lure of weatherproof shoes is strong. Anything that can stem the soggy tide is worth a go, right?

This isn’t as simple an answer as it sounds. In the past, a lot of runners—that includes me—felt waterproof shoes came with too many trade-offs, like thicker, heavier uppers that change the feel of your shoes or a tendency to run hot and sweaty. In general, weatherproof shoes are less comfortable.

But waterproofing technology has evolved, and it might be time for a rethink. Winterized shoes can now be as light as the regular models, breathability is better, and the comfort levels have improved. Brands are also starting to add extra puddle protection to some of the most popular shoes. So it’s time to ask the questions again: Just how much difference does a bit of Gore-Tex really make? Are there still trade-offs for that extra protection? And is it really worth paying the premium?

I spoke to the waterproofing pros, an elite ultra runner who has braved brutal conditions, and some expert running shoe testers. Here’s everything you need to know about waterproof running shoes in 2026. Need more information? Check out our guide to the Best Running Shoes, our guide to weatherproof fabrics, and our guide to the Best Rain Jackets.

How Do Waterproof Running Shoes Work?

On a basic level, waterproof shoes add extra barriers between your nice dry socks and the wet world outside. If you’re running through puddles deep enough to breach your heel collars, you’re still going to get wet feet. But waterproof shoes can protect against rain, wet grass, snow, and smaller puddles.

Gore-Tex is probably the most common waterproofing tech in footwear, but it’s not the only solution in town. Some brands have proprietary tech, or you might come across alternative systems like eVent and Sympatex. That GTX stamp is definitely the one you’re most likely to encounter, so here’s how GTX works.

The water resistance comes from a layered system that is composed of a durable water repellent (DWR) coating to the uppers with an internal membrane, along with other details like taped seams, more sealed uppers with tighter woven mesh, gusseted tongues, and higher, gaiter-style heel collars.
