## Updates from LaunchDarkly
### 2026-04-29 23:45 UTC: resolved
We've identified an infrastructure issue that caused some 503 responses in feature flagging streaming client initialization on the US LaunchDarkly instance between 16:45 and 17:05 PT. SDKs should automatically retry initialization in most cases.
