AWS apologises for 14-hour outage and sets out causes of US datacentre region downtime | Computer Weekly


Amazon Web Services (AWS) has issued an apology to its customers inconvenienced by its largest US datacentre region suffering a 14-hour outage on 20 October, in a blog detailing the precise nature of the technical difficulties its services suffered.

As previously reported by Computer Weekly, the outage originated in the public cloud giant’s US-East-1 datacentre region in North Virginia, and caused large-scale disruption to a host of companies across the world, including in the UK.

Social media and communications services such as Snapchat and Signal suffered disruption to their services, as did Amazon-owned internet entities such as its retail site, Ring doorbell and Alexa services.

Financial services provider Lloyds Bank Group, along with its Halifax and Royal Bank of Scotland subsidiaries, and the government tax collection agency HM Revenue and Customs, were also affected in the UK by the outage.

As a result, HM Treasury is now facing calls to give an account as to why – given its role as a major supplier of cloud services to the UK financial services sector – AWS has not been called into scope of its Critical Third Parties (CTP) regime before now.

The initiative gives HM Treasury powers to designate suppliers to the financial services sector as being CTP, meaning their activities can be brought into the supervisory scope of the UK’s various financial regulators.

The intention being that doing so might help better manage any potential risks to the stability and resilience of the UK financial system that might arise as a result of a third-party supplier suffering from service disruption, as happened with AWS this week.

The company has now published an extensive post-event summary document, which confirms the outage occurred in three distinct phases as a result of issues occurring within several parts of its infrastructure.

As such, the company said that just before 8am UK time on 20 October, its fully managed, serverless, NoSQL database offering Amazon DynamoDB began to experience increased application programming interface (API) error rates, which lasted for just under three hours.

Then, from around 1pm UK time on 20 October, some of the network load balancers (NLB) within its US-East-1 region started to experience increased connection errors, which persisted until around 10pm the same day. “This was caused by health check failures in the NLB fleet, which resulted in increased connection errors,” the summary document stated.

In addition to this, AWS said issues occurred when attempts were made to launch instances of its Elastic Cloud Compute (EC2) virtual servers, which is an issue that persisted from around 10.30am on 20 October UK time until 6.30pm.   

“New EC2 instance launches failed and, while instance launches began to succeed from 10:37 AM PDT [6.37pm UK time], some newly launched instances experienced connectivity issues which were resolved by 1:50 PM [9.50pm UK time],” the summary document continued.

It also confirmed that other AWS services hosted within US-East-1 suffered knock-on effects as a result of the issues experienced by DynamoDB, EC2 and its network loan balancing setup.

“We are making several changes as a result of this operational event,” the company said. “As we continue to work through the details of this event across all AWS services, we will look for additional ways to avoid impact from a similar event in the future, and how to further reduce time to recovery.”

The company then concluded the summary document with an apology to any customers affected by the outage.

“While we have a strong track record of operating our services with the highest levels of availability, we know how critical our services are to our customers, their applications and end users, and their businesses,” said the summary document. “We know this event impacted many customers in significant ways. We will do everything we can to learn from this event and use it to improve our availability even further.”

I Tested Garmin Watches for a Decade While Hiking, Biking, and Climbing. Here’s What You Should Buy

I Tested Garmin Watches for a Decade While Hiking, Biking, and Climbing. Here’s What You Should Buy


Last year, Garmin introduced a Pro version that incorporates the inReach’s satellite communications savvy. Not only does it cost at least $400 more than the Apple Watch Ultra and $200 more than the regular Fenix 8, but you also have to pay for the inReach subscription plan, which has several tiers and ranges from $8/month to $50/month depending on whether you want features like unlimited texting or sending photo messages.

What you get for this mind-boggling price is a sports watch that can do anything and everything. It has best-in-class battery life (every Fenix can last for weeks on a single charge, and up to a month with solar charging) and features like the depth sensor from Garmin’s Descent line, which means this watch works as a full-on dive computer for scuba and free diving. It has a microphone and speaker for basic voice commands (although no onboard cellular connectivity), the surprisingly useful built-in LED flashlight, and Garmin’s signature built-in topographic maps, 24/7 health monitoring, and tracking for over a hundred different activities.

I’ve taken the 51-mm version on pretty much every outdoor sport—snowboarding, trail running, mountain biking, and rock climbing. Every time I use it, its capabilities far outclass my own. I have irritated many a fellow climber by attempting to track route difficulty, duration, and falls while integrating my Body Battery metrics and so on. The danger is always that you’ll spend more time fiddling with your Garmin Fenix 8 than you do with your actual sport. I have the version with the sapphire glass face and the titanium bezel, and have smashed it into rock faces with nary a scratch. If you’re up for paying the price and want a good-looking watch that will last forever (I have friends who are still wearing their Fenix 5s and 6s, and honestly, they’re fine), this is the one to get.

Best Running Watch

The Garmin Forerunner series launched in the early 2000s and has become the quintessential runner’s watch. Like all Garmins, the Forerunner comes in a range of price points, each offering different features. Last year, Garmin released the Forerunner 570 ($550), a midrange model with no LED flashlight or onboard maps, and the Forerunner 970 ($750), which is the premium version. Before I go into detail about why the Forerunner 970 is the best option, I should also say that I have tested many previous Garmin Forerunners at various price points. If you’re not a triathlete, the older Forerunners are still worth considering, and the entry-level $200 Forerunner 165 is aimed explicitly at runners, instead of including triathletes as the more expensive models do.

Save Up to 40% With These Acer Promo Codes and Discounts


Acer is one of the top largest PC manufacturers in the world, perhaps best known for its gaming line and budget-friendly options. If you’ve already got your eye on an Acer product like a laptop or monitor, and are shopping at the company’s online storefront, you should be using one of these Acer promo codes and coupons to save some cash on your purchase.

Save 40% on Accessories When You Build an Acer Bundle

If you’re buying from Acer, you’re most likely shopping for either a desktop PC or laptop. With this discount, you can get a really solid deal on accessories if you bundle it with a mouse, laptop bag, or headset. When you go to purchase a PC, just click “Build Bundle” and you’ll see some of the eligible options, all of which are reduced by 40%. The Nitro Mechanical Keyboard, for example, goes from $50 to just $30. That 40% is a real discount, too, as that same keyboard costs $50 on Amazon when I checked.

Beyond peripheral add-ons, you can also save 10% off Acer Care Plus extended service plans or McAfee LiveSafe antivirus subscriptions. You can bundle up to five products together to save the most money. If you’re headed off to college (or have a kid in the family), a bundle like this can get you everything you need for a gaming or studying setup on the go.

Shop Rotating Weekly Deals on Monitors and Gaming Gear

Acer’s PC gaming offerings come in either the flagship Predator brand or the budget-tier Nitro. Acer offers rotating weekly deals on everything from monitors to gaming laptops, some of which are my favorites that I’ve tested in their given category. The Acer Nitro V 16, for example, was a budget gaming laptop that I recommended quite a lot last year because of its incredible price. The one I tested was the entry-level version with an Nvidia RTX 5050 inside, but Acer has the RTX 5060 model in its own storefront. It’s $100 off right now at $1,200, which comes with 16 GB of RAM and a terabyte of storage. In fact, it’s only $30 more than the RTX 5050 model, despite offering a significant jump in gaming performance. These discounts are reflected right on the product pages, so there’s no promo code, discount code, or coupon code required.

Acer has a wide selection of monitors available, too, whether that’s a massive 49-incher or a more modest 27-inch gaming workhorse. One of my favorite discounts I saw right now was the Acer Nitro XV2, a 27-inch 1440p display with a 300 Hz refresh rate. It’s 44% off at the time of writing, bringing the price down to just $250. Because these discounts are swapped out on a weekly basis, it’s worth checking back to see if the product you’re eyeing has a new discount.

Select Customers Can Get 15% Off Their Purchase

Acer also offers a number of added discounts at checkout, including 15% off for students. Students will need to verify through Student Beans or SheerID. Because a lot of the devices Acer offers are budget-friendly, they can be attractive for students, and the extra 15% off is the icing on the cake.

We tested the Acer Swift 16 AI last year and really enjoyed the high-resolution, OLED screen and impressively quiet performance. Acer has the smaller version of this same laptop available, the Swift 14 AI, which is currently $150 off. You also might check out the Acer Chromebook Plus 514, a laptop we liked quite a bit when we reviewed it in 2024.

Acer offers this same 15% discount for active duty military, veterans, and their families. It also applies to healthcare professionals, which can be verified through its healthcare discount portal.

AI Research Is Getting Harder to Separate From Geopolitics

AI Research Is Getting Harder to Separate From Geopolitics


The world’s top AI research conference, the Conference on Neural Information Processing Systems—better known as NeurIPS—became the latest organization this week to become embroiled in a growing clash between geopolitics and global scientific collaboration. The conference’s organizers announced and then quickly reversed controversial new restrictions for international participants after Chinese AI researchers threatened to boycott the event.

“This is a potential watershed moment,” says Paul Triolo, a partner at the advisory firm DGA-Albright Stonebridge who studies US-China relations. Triolo argues that attracting Chinese researchers to NeurIPS is beneficial to US interests, but some American officials have pushed for American and Chinese scientists to decouple their work—especially in AI, which has become a particularly sensitive topic in Washington.

The incident could deepen political tensions around AI research, as well as dissuade Chinese scientists from working at US universities and tech companies in the future. “At some level now it is going to be hard to keep basic AI research out of the [political] picture,” Triolo says.

In its annual handbook for paper submissions, issued in mid-March, NeurIPS organizers announced updated restrictions for participation. The rules stated that the event could not provide services including “peer review, editing, and publishing” to any organizations subject to US sanctions, and linked to a database of sanctioned entities. It included companies and organizations on the Bureau of Industry and Security’s entity list and those on another list with alleged ties to the Chinese military.

The new rules would have affected researchers at Chinese companies like Tencent and Huawei who regularly present work at NeurIPS. The database also includes entities from other countries such as Russia and Iran. The US places limits on doing business with these organizations, but there are no rules around academic publishing or conference participation.

The NeurIPS handbook has since been updated to specify that the restrictions apply only to Specially Designated Nationals and Blocked Persons, a list used primarily for terrorist groups and criminal organizations.

“In preparing the NeurIPS 2026 handbook, we included a link to a US government sanctions tool that covers a significantly broader set of restrictions than those NeurIPS is actually required to follow,” the event’s organizers said in a statement issued Friday. “This error was due to miscommunication between the NeurIPS Foundation and our legal team.”

Before they reversed course, the conference organizers initially said that the new rule was “about legal requirements that apply to the NeurIPS Foundation, which is responsible for complying with sanctions,” adding that it was seeking legal consultation on the issue.

Immediate Backlash

The new rule drew swift backlash from AI researchers around the world, particularly in China, which produces a large quantity of cutting-edge machine learning papers and is home to a growing share of the world’s top AI talent. Several academic groups there issued statements condemning the measure and, more importantly, discouraging Chinese academics from attending NeurIPS in the future. Some urged Chinese academics to contribute instead to domestic research conferences, potentially helping increase the country’s influence in relevant science and tech fields.

The China Association of Science and Technology (CAST), an influential government-affiliated organization for scientists and engineers, said Thursday that it would stop providing funding for Chinese scholars traveling to attend NeurIPS and would use the money instead to support domestic and international conferences that “respect the rights of Chinese scholars.”

CAST also said it will no longer count publications at the 2026 NeurIPS conference as academic achievements when evaluating future research funding. It’s unclear if the organization will reverse course now that NeurIPS has walked back the new rule.
