Service disruption: Increased Error Rates

Update timeline

1. monitoring Mar 01, 2026, 08:14 PM UTC

   We are aware that some customers are experiencing errors when calling EC2 APIs, specifically networking related APIs (AllocateAddress, AssociateAddress, DescribeRouteTable, DescribeNetworkInterfaces). We are actively working on multiple paths to mitigate these issues. For customers experiencing throttling errors on the AllocateAddress APIs, we recommend retrying any failed API requests. We are deploying a configuration change to mitigate the AssociateAddress API errors and expect recovery in the next few hours. DescribeRouteTable and DescribeNetworkInterfaces API calls without specifying zone, Interface or Instance IDs are expected to fail until we restore the impacted zone. We recommend customers to pass these IDs explicitly in these API requests. For customers that can, we recommend considering using alternate AWS Regions. We will provide another update by 3:30 PM PST, or sooner if we have more to share.
