Amazon’s cloud services unit AWS has said it has resolved the issue behind a major outage that had led to connectivity issues for a large number of popular websites and apps around the world.
In an update on its status page on Monday, Amazon Web Services (AWS) said the “underlying DNS issue has been fully mitigated, and most AWS Service operations are succeeding normally now”.
“Some requests may be throttled while we work toward full resolution,” it added.
The company said the issue had centred on DynamoDB, a database service in one of Amazon’s main data centres in Virginia in the United States, known as US-EAST-1. It recommended that people still experiencing issues relating to the outage try flushing their DNS caches.
The outage had caused major issues for popular websites and apps around the world. Platforms including AI startup Perplexity, trading app Robinhood, messaging app Signal and crypto exchange Coinbase all reported issues that they said were due to the AWS outage.
“Perplexity is down right now. The root cause is an AWS issue. We’re working on resolving it,” Perplexity CEO Aravind Srinivas said in a post on X.

AWS is one of the giant cloud computing service providers, competing with Google and Microsoft’s cloud services to offer on-demand computing power, data storage and other digital services to companies and institutions.
Issues with its servers can wreak havoc on the web, with so many companies relying on its infrastructure to function.
PSA: we are aware that Signal is down for some people. This appears to be related to a major AWS outage. Stand by.
