Between 16:35-17:03 UTC, Chicago region experienced about 11% failure rates in API errors, failed agent dispatches, and issues connecting to rooms. We faced another wave of the same issue between 17:47-17:53 UTC where the failure rates were less than 10%. Room Service APIs called from other regions targeting to a room hosted in Chicago region were also affected during this period. API requests made with recent server SDK versions are automatically retried in other regions, so customers on those versions should not have seen these errors. The last related errors occurred at 17:53 UTC, and all affected services are operating normally since. We will share a detailed RCA with more information soon.
