Our performance monitors are flickering in red because a large but random portion of requests suffer from very slow (250ms connect, 250ms SSL then +500ms to first byte than usual) connections
What steps have you taken to resolve the issue?
Tested from different locations (Datadog in both AWS and GCP regions), and Pingdom from another region to double-check.
Healthcheck Insights within Cloudflare show a steady <50ms to Origin.
Cloudflare status page is silent but everything suggests an issue with CDN. The slow SSL handshake seems to point finger at it.
What are the steps to reproduce the issue?
Test browser every minute.
Response time : 80% under 600ms. 20% between 2000 and 3000ms.
We have been experiencing a similar drastic increase in latency since yesterday (2024-10-24) - this issue is affecting only domains and endpoints that are proxied through Cloudflare.
