Service impact: Increased connectivity issues and API Error Rates

Update timeline

1. monitoring Mar 02, 2026, 07:09 AM UTC

   We are investigating connectivity and power issues affecting APIs and instances in a single Availability Zone (mes1-az2) in the ME-SOUTH-1 Region due to a localized power issue. Existing instances in this zone will also be affected. Other AWS Services may also be experiencing increased errors and latencies for their workflows, and we are working to route requests away from this affected Availability Zone. We recommend customers make use of other Availability Zones at this time. During this time, we are also experiencing delays in propagating DNS changes for Route53 to pops (Points of Presence) in ME-SOUTH-1. Targeting new launches using RunInstances in the remaining AZs should succeed. Existing instances in the other AZs are not affected.
