Is LaunchDarkly down?

Server-side streaming requests experienced elevated error rates between approximately 12:00 p.m. and 12:12 p.m. PDT, and some SDKs establishing new streaming connections may have been unable to connect. Polling request error rates remained below 1% throughout the incident. No customer data was lost or compromised. We apologize for the disruption.

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%. 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.

Emails sent by LaunchDarkly — including sign-up verification, password reset, teammate invitation, and workflow notification emails — are currently failing to deliver due to an authentication issue with an upstream email delivery provider. We have identified the cause and are working to restore delivery. Feature flag delivery, SDKs, and the LaunchDarkly application itself are not affected. If you are trying to complete sign-up or reset a password, those emails will not arrive until this is resolved. Once delivery is restored, we will re-send affected verification and password reset emails. Next update within 2 hours.

Email delivery has been restored as of 2:32 PM UTC. Sign-up verification, password reset, teammate invitation, and notification emails are sending normally again. We are re-sending sign-up verification and password reset emails that failed to deliver during the incident window (August 22, 11:48 PM CDT through today). If you attempted to sign up or reset a password during that period and haven't received an email within the next few hours, please retry the action or contact support. We are continuing to monitor email delivery closely and will post a final update once we've confirmed sustained recovery.

We're experiencing a service degradation which can result in Flag updates via the Polling API to be delayed.

We've identified the issue and have mitigated it. Monitoring for a while to make sure things stabilise.

This incident has been resolved.

Flag Updates are currently delayed in the us-east-1 region. We are investigating the issue.

We investigated elevated error rates reported for mobile SDK flag delivery in US East. We've confirmed that flag delivery itself was not impacted. No customer action is required and we are monitoring the situation.

The issue is being marked as resolved. We're seeing improved latencies and our systems have recovered.

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.

We are continuing to investigate this issue.
