On May 7th Coinbase experienced service disruptions. Here’s a quick summary of what happened: → Around 8PM ET, Coinbase systems flagged high error rates across multiple services. → We traced these errors to amazon failures in Availability Zone (use1-az4) in the AWS US-EAST-1 Region. → Coinbase systems are designed to be resilient to a single zone outage, and are designed to recover quickly if this happens. → In this case, we observed failures impacting multiple AWS zones, which caused an extended outage of core trading services. → Coinbase users experienced an extended outage while the AWS team worked to restore temperature controls and other Amazon Managed Services. This primary issue is now fully resolved - thank you for your patience. If you have any outstanding questions about your account, please reach out to Coinbase Support, we’re ready to help. Our team will conduct a full analysis. Details may change as our investigation progresses and more information is received from AWS’s official retrospective, once published.
