Issues with Private Network CIDR Routes for WARP Connector

Cloudflare was investigating an issue affecting WARP Connector where traffic destined for specific Private IP CIDR ranges failed to route correctly for a small subset of accounts. This occurred between 2025-11-20 18:09 UTC to 2025-11-21 13:44 UTC. During this window, affected WARP Connectors may have appeared connected but failed to pass traffic to specific internal resources. Our engineering team identified the underlying cause and deployed a fix. This issue is fully resolved now.
