We wanted to provide additional information for the event affecting some RDS database instances in a single Availability Zone (euw2-az2) in the EU-WEST-2 Region. Starting at 2:05 AM PDT we experienced power and network connectivity issues for some database instances within the affected Availability Zone. The affected Multi-AZ databases failed over to another Availability Zone as expected, and only Single-AZ databases remained affected. By 5:30 AM PDT, power and networking connectivity had been restored to the majority of affected Single-AZ database instances. We are continuing to work to recover the remaining instances.
