Cloudflare is investigating an issue where Health Check Events analytics are returning incorrect round-trip time (rttMs) values. Affected users may observe abnormally large values in Health Check latency analytics on the dashboard. This does not affect the actual health check functionality or monitoring — health checks continue to operate normally. The issue is limited to the analytics data displayed for health check events.

Between 14:41 and 16:34 UTC on April 9th, 2026, we experienced an elevated level of HTTP 5xx errors affecting traffic through our Philadelphia (PHL) data center. The issue has been mitigated now.
Between 19:47 and 21:57UTC on April 8, 2026, Cloudflare identified and mitigated a network performance issue specifically affecting our Miami and Atlanta regions. Users may have experienced increased latency or intermittent connectivity due to degraded routing paths in the Southeast. Our engineering team has since stabilized the connection and confirmed that all systems are back to full operational capacity; we will continue to monitor these nodes closely to ensure ongoing performance.
