```diff
+ Server-side streaming began rejecting new connections across all commercial regions, causing 500/503 errors for customers attempting to establish new SDK streaming connections for a brief period of time. Detailed timelines of the incident: - us-east-1 : 7:53 AM  PST to 8:24 AM PST - ap-southeast-1: 7:53 AM  PST to 7:55 AM PST - eu-west-1: 7:53 AM  PST to 8:35 AM PST The team was quickly able to deploy the mitigation before an incident could be declared in our status pages, this is why we're posting it, retroactively.
