Dan Milmo
A major internet outage has hit dozens of websites and apps around the world, with users reporting troubles getting online after problems at Amazon’s cloud computing service.
The affected platforms include Snapchat, Roblox, Signal and Duolingo as well as a host of Amazon-owned operations including its main retail site and the Ring doorbell company.
In the UK, Lloyds bank was affected as well as its subsidiaries Halifax and Bank of Scotland, while there were also reports of problems accessing the HM Revenue and Customs website on Monday morning. Also in the UK, multiple Ring users took to social media to complaint their doorbells were not working.
In the UK alone reports of problems on individual apps ran into the tens of thousands for each platform. More here:
Key events
Today’s outage does not appear to be caused by a cyber-attack, reports Dr Amro Al-Said Ahmad, a lecturer in computer science at Keele University, who explains:
The issue appears to be related to AWS (Amazon Web Services), which hosts the infrastructure that underpins much the internet services. It allows customers to deploy their own servers, databases, and storage without the need to own physical infrastructure.
According to AWS’s latest update, they have identified the root cause of the outage. It appears to be significant error rates for requests made to their data storage service, DynamoDB, in the US-EAST region. Therefore, the outage was not caused by cyber-related attacks, as was speculated.
Resolving major outages like this presents significant challenges because of the cloud complexity and its dependencies. Furthermore, diagnoses need to see how much third-party platforms are dependent on AWS cloud. The solution and fix will involve thorough diagnostics, testing, and deployment of a reliable fix, which, based on past incidents in the industry, can take anywhere from hours to several days.
UK ‘in contact’ over Amazon Web Services incident

The UK government has said it is in contact with Amazon over today’s internet outage.
A government spokesperson says:
“We are aware of an incident affecting Amazon Web Services, and several online services which rely on their infrastructure. Through our established incident response arrangements, we are in contact with the company, who are working to restore services as quickly as possible.”

The AFP newswire points out that there have also been reports of disruption at Amazon Prime, Alexa, Reddit, various video streaming platforms such as Hulu and Disney+, as well as messaging app Signal and Delta Air Lines, as well as the services we’ve flagged in this blog already.
They also cite Downdetector data showing reports of disruption at Whatsapp (although mine has been working OK this morning) and Tinder (can’t help with this one, sorry).
AWS: global services and features that rely on US-EAST-1 have also recovered.
Amazon Web Services has now suggested that the recovery from today’s outage at its US-EAST-1 region in Virginia is on track.
Its operational status page now says:
We continue to observe recovery across most of the affected AWS Services.
We can confirm global services and features that rely on US-EAST-1 have also recovered. We continue to work towards full resolution and will provide updates as we have more information to share.
HMRC: We’re hit by global issues affecting Amazon Web Services
A spokesperson for HMRC, the UK tax authority, has confirmed that its online service has been disrupted by the problem at Amazon Web Services.
An HMRC spokesperson said:
“We’re aware that customers are having problems accessing our online services, as part of global issues affecting Amazon Web Services. We’re working urgently with them on this matter.
“Our phonelines are currently busy as a result, so for anything that isn’t urgent we recommend calling at a later time.”
AI startup Perplexity, cryptocurrency exchange Coinbase and trading app Robinhood have all attributed outages today to AWS, Reuters reports.
Perplexity CEO Aravind Srinivas said in a post on X:
“Perplexity is down right now. The root cause is an AWS issue. We’re working on resolving it.”

The technical problem at Amazon Web Services looks like “an IT issue on the database side,” reports Rafe Pilling, director of threat intelligence at security firm Sophos.
Pilling explains:
“When anything like this happens the concern that it’s a cyber incident is understandable. AWS has a far reaching and intricate footprint, so any issue can cause a major upset. In this case it looks like it is an IT issue on the database side and they will be working to remedy it as an absolute priority.”
AWS: We are seeing significant signs of recovery
Just in: Amazon Web Services report that they are seeing “significant signs of recovery” in the operational issue that appears to have disrupted services across the internet today.
In an operational update, AWS says:
We are seeing significant signs of recovery. Most requests should now be succeeding. We continue to work through a backlog of queued requests. We will continue to provide additional information.
That follows an earlier update announcing that some ‘early signs of recovery’ were being detected, with AWS saying:
We have applied initial mitigations and we are observing early signs of recovery for some impacted AWS Services. During this time, requests may continue to fail as we work toward full resolution. We recommend customers retry failed requests. While requests begin succeeding, there may be additional latency and some services will have a backlog of work to work through, which may take additional time to fully process.
Update: Duolingo streaks should still be safe despite the technical problems hitting the site today.
One user received this ‘quick maintainance break!’ page, which reassures users that their streak is protected today ‘just in case!’.
Problems are also being reported at Depop, the secondhand clothing platform.
According to the Down for Everyone or Just Me site, problems have been reported by users in Australia, New Zealand, the US and the UK, highlighting how today’s outage is a global problem.
