AWS Outage May 2026: Lessons for Database Disaster Recovery

In May 2026, a thermal event in an Amazon data center in Northern Virginia led to a significant outage impacting multiple companies, including Coinbase, FanDuel, and CME Group, due to failed cooling units in the AWS availability zone use1-az4. This incident highlighted the vulnerability of relying on single-region setups for mission-critical workloads, as Coinbase experienced a seven-hour offline period, and others faced operational challenges. The outages underscored the distinction between high availability and disaster recovery, emphasizing that multi-region disaster recovery plans are essential for resilience. SingleStore's Smart DR provides a solution by offering cross-region disaster recovery with asynchronous database replication and a target recovery point objective (RPO) of up to 10 minutes, while also maintaining low costs until failover. The broader lesson from the event is the necessity of proactive disaster recovery planning, as relying on a single provider's reliability does not equate to overall resilience, and companies must actively manage where their data resides and how swiftly it can be recovered in different regions.
