## Timeline of updates

- **resolved** 2025-10-21 10:00 UTC: This incident has been resolved. One of our mitigation steps involved adding new IPs for stream.launchdarkly.com to our public IP list. Some customers may need to update IP allowlists in their firewalls or proxy servers in order for their services to continue establishing streaming connections from server side SDKs to LaunchDarkly without disruption. Please refer to documentation at https://docs.launchdarkly.com/home/advanced/public-ip-list for more information. Refer to https://app.launchdarkly.com/api/v2/public-ip-list for complete list of public IPs. Customers who switched from streaming to polling mode as a workaround are clear to revert back to streaming mode.

_From the vendor’s published history: only the final update text is available for incidents before Rewindex began polling this page._
