Amazon's cloud unit, AWS, reported an outage at a data center in northern Virginia on Thursday. The incident caused issues for derivatives marketplace CME Group and cryptocurrency exchange Coinbase.
AWS said the problem stemmed from rising temperatures in a single data center. It reported early signs of recovery after bringing additional cooling capacity online. The company shifted traffic away from the affected Availability Zone for most services.
Coinbase confirmed the AWS outage caused degraded performance for some users, but assured that customer funds remained safe. The exchange said it was working to re-enable trading shortly.
CME Group, the world's largest derivatives marketplace, acknowledged technical and latency issues but did not identify the cause. It reported completing essential maintenance, allowing users to log back into its CME Direct platform.
This disruption follows a major AWS outage in October 2024 that affected thousands of sites. That event was the largest internet disruption since the CrowdStrike malfunction in 2024 highlighted the vulnerability of interconnected technologies. CME also suffered a prolonged outage in November 2024 due to a cooling failure at a CyrusOne data center.
