en.Wedoany.com Reported - On May 8, cloud services for Amazon Web Services, the cloud computing division of U.S.-based Amazon, largely returned to normal. A day earlier, a data center operated by the company in Northern Virginia experienced a service disruption caused by rising temperatures, impacting multiple businesses including the cryptocurrency exchange Coinbase.

According to the AWS official status page, the failure occurred around 5:25 PM Eastern Time on May 7, with the impact concentrated in a single Availability Zone (use1-az4) within the US-EAST-1 Region. AWS explained in its incident report that elevated temperatures were observed inside the data center, which in some cases caused server instances within the Availability Zone to fail. EC2 instances and EBS volumes hosted on the affected hardware were impaired due to power loss during the thermal event.

Following the failure, an AWS engineering team began working to restore cooling system operations. The company reported that "power has been restored to a subset of the affected infrastructure, and some early signs of recovery have been observed," but the full restoration of the cooling system progressed slower than initially expected. As part of the recovery measures, AWS shifted traffic for most services away from the affected Availability Zone to other normally operating zones. As of the morning of May 8, some services such as SageMaker, OpenSearch Service, ElastiCache, and EC2 instances were still experiencing varying degrees of impact.

This service disruption affected multiple enterprise users. Cryptocurrency trading platform Coinbase stated that due to the AWS failure, some users experienced degraded trading functionality, and the platform temporarily suspended its order matching feature. Coinbase declared on social media that customer funds remained secure. Sports betting platform FanDuel was also reported to have experienced technical issues from the same event, with users temporarily unable to log in normally. As of the morning of May 8, both Coinbase and FanDuel indicated that the major issues had been resolved and business operations had returned to normal.
