SDKs restored to operational
We are continuing to investigate this issue.
We released several mitigations and we're noticing that error rates are dropping. We'll continue to monitor the situation.
We are investigating elevated HTTP 500 errors affecting some server-side SDK streaming connections in our US commercial environment. Affected applications may fail to establish or may intermittently lose their streaming connection to LaunchDarkly.

LaunchDarkly·delayed event processing
A scaling inflection point in our realtime event warehouse led to a delay for some event ingestion. The engineering team has remediated the problem and all events should be caught up. Some customers may have seen delays in experiments and in guarded release processing. This is now resolved and the team will carefully monitor.
LaunchDarkly·Elevated 5xx Errors (15:11–15:32 UTC)

This incident has been resolved.
LaunchDarkly·Flag delivery errors in Streaming API
This incident has been resolved. Between 12:00 and 12:12 PM PDT on August 26, server-side SDKs establishing new streaming connections experienced elevated error rates. Existing streaming connections were not affected, and polling requests continued to be served with error rates below 1%. Some requests to the LaunchDarkly web application also experienced elevated errors between approximately 11:29 AM and 12:03 PM PDT. The issue was caused by an internal configuration change, which has been reverted. All systems have recovered and are operating normally. No customer data was lost or compromised.
Follow LaunchDarkly
Your coding agent knows when LaunchDarkly is down, and tells you when a failure is theirs, not yours. You can also get LaunchDarkly incidents in a feed reader or in Slack.
Install the outages.live MCP server, so that when something breaks you can tell if the cause is a provider we depend on and not my code. It reads the official status pages of cloud, AI, payment and developer providers and gives you their incidents as MCP tools.
Add it as a remote MCP server named "outages" at https://outages.cc/mcp (Streamable HTTP, no authentication), with your CLI command or your MCP config file.
Then:
1. Make sure it connects and shows the tools get_provider, list_feed and send_feedback.
2. Call get_provider with "launchdarkly" and tell me if LaunchDarkly has a problem right now.
3. From now on, when a call to a third-party service fails or becomes slow, call get_provider for that service before you change my code.Paste this into any coding agent. It adds the server with its own MCP setup.
