AWS outage list: Roblox, Fortnite, Snapchat and more

Amazon Web Services (AWS) is not having a great start to the week.

A massive internet outage hit AWS-powered platforms in the early hours of Monday morning, affecting a large number of popular sites, games and services including the likes of Fortnite, Snapchat, and HBO Max. Of course, people are reacting online.

AWS posted on a company dashboard at 5:01 a.m. ET, "We have identified a potential root cause for error rates for the DynamoDB APIs in the US-EAST-1 Region," which the company said was "related to DNS resolution." AWS added it was working to resolve the issue.

At 5:27 a.m. ET, the company reported "significant signs of recovery" across the affected sites listed below, and that "most requests should now be succeeding. Then, at 6:35 a.m. ET, Amazon said, "The underlying DNS issue has been fully mitigated, and most AWS Service operations are succeeding normally now." However, the company noted that "some requests may be throttled while we work toward full resolution."

Mashable reached out to Amazon for further comment and was directed to the AWS Health Dashboard.
