Coinbase has resumed trading across all markets; the incident is related to a broader AWS outage.

Coinbase stated that, at approximately 8:00 a.m. Beijing Time on May 8, its systems detected elevated error rates across multiple services. The issue was subsequently traced to AWS’s US-EAST-1 Region Availability Zone use1-az4. Although Coinbase’s systems were originally designed to recover from failures in a single availability zone, this incident affected multiple availability zones, resulting in an extended outage of core trading services. The primary issues have now been fully resolved. The team will conduct a comprehensive postmortem analysis and provide further updates once AWS releases its official post-incident report.
