Resolved - This incident has been resolved.
Nov 18, 2025 - 19:28 UTC
Update - Cloudflare services are currently operating normally. We are no longer observing elevated errors or latency across the network.
Our engineering teams continue to closely monitor the platform and perform a deeper investigation into the earlier disruption, but no configuration changes are being made at this time.
At this point, it is considered safe to re-enable any Cloudflare services that were temporarily disabled during the incident. We will provide a final update once our investigation is complete.

Update - We continue to see errors drop as we work through services globally and clearing remaining errors and latency.
Nov 18, 2025 - 16:46 UTC
Update - We continue to see errors and latency improve but still have reports of intermittent errors. The team continues to monitor the situation as it improves, and looking for ways to accelerate full recovery.
