Inaccurate values in Health Check Events Analytics

This incident has been resolved.

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.
