Started May 05, 2026, 04:49 PM UTC· resolved May 05, 2026, 10:25 PM UTC
- investigating May 05, 2026, 04:49 PM UTC
Cloudflare is investigating connectivity issues affecting Cloudflare Tunnel and Browser Isolation. This issue is currently limited to the establishment of new connections. Customers may experience errors or timeouts when attempting to start new tunnel replicas via cloudflared or when initiating new Browser Isolation sessions. Existing tunnels and active sessions are not affected and continue to operate normally. Our engineering team is actively investigating the root cause, and we will provide additional updates as soon as more information is available.
- investigating May 05, 2026, 04:58 PM UTC
We are continuing to investigate this issue.
- identified May 05, 2026, 05:24 PM UTC
The connectivity issues affecting Cloudflare Tunnel and Browser Isolation have stabilized, and we have identified the root cause. Our investigation confirms that internal service restarts across our edge infrastructure led to significant connection churn. This caused active Cloudflare Tunnel connections and Browser Isolation sessions to disconnect and attempt to re-establish simultaneously. While this surge initially resulted in elevated error rates and registration failures, service health has now recovered, and connection success rates have returned to normal levels. Most customers should see services operating normally at this time.
