Coinbase outage linked to AWS multi-zone failure disrupts trading and transfers

A Coinbase outage disrupted trading, fund transfers, and mobile app access late Thursday into early Friday. Coinbase said the Coinbase outage was caused by AWS failures in the US-EAST-1 region affecting multiple availability zones, including use1-az4. The disruption started around 8 p.m. ET after Coinbase detected elevated error rates across several services. Downdetector showed complaint spikes around 6 p.m. ET and they stayed elevated overnight. Users mainly reported issues with fund transfers (~33%), trading (~33%), and the Coinbase mobile app (~29%). Coinbase said the primary problem has been resolved. It added that its systems can recover from a single availability-zone outage, but this event became extended because AWS failures hit multiple zones while restoration was underway. The incident follows an earlier October AWS-related outage that briefly took Coinbase (and Robinhood) offline. For traders, this Coinbase outage is a reminder that exchange infrastructure risk can quickly translate into liquidity frictions, potential order execution delays, and transfer setbacks during volatility. Separately, the broader context includes recent financial pressure and prior cost-cutting, which may heighten scrutiny of Coinbase’s operational resilience.
