Coinbase Says May 7 Trading Outage Stemmed From Multi-Zone AWS Failures in US-EAST-1

Coinbase said a May 7 incident disrupted core trading services after errors spread across multiple Amazon Web Services availability zones, with the issue traced to use1-az4 in the US-EAST-1 region. The exchange said its recovery design handled a single-zone failure, but this event exceeded those conditions, leading to trading interruptions until markets were gradually restored. Coinbase added it will complete a full review while awaiting AWS's official retrospective.
