Coinbase experienced a significant service outage on May 7, 2026, disrupting trading and platform access for several hours. CEO Brian Armstrong addressed the incident, attributing the cause to an overheated rack in an AWS data center following multiple cooling failures. The outage affected spot trading, Prime membership services, international trading, and derivatives exchanges. Armstrong emphasized that while Coinbase's systems are designed to withstand the failure of any single AWS Availability Zone, not all systems achieved this during the incident. He highlighted the need to reassess trade-offs in their architecture to minimize latency and improve client co-deployment. Armstrong assured users that no data loss occurred and that the team is already implementing follow-up steps to prevent future disruptions.
