We are investigating an increase in SDK error rates affecting a small portion of requests, currently estimated at less than one percent. SDKs will automatically retry these errors, so the primary customer impact is expected to be longer SDK initialization times rather than request failures. We believe the issue is related to an ongoing incident affecting one of our vendors. Our team is actively working to mitigate the impact and will provide additional updates as more information becomes available.
