[Paris] Increased TLS handshake latency on public reverse proxies

Fixed · Reverse Proxies · Global

Resolved:

Public load balancers in the Paris region are experiencing increased TLS handshake times since 08:23 UTC, resulting in:

  • TLS handshake timeouts for some HTTPS queries
  • Extended HTTPS request processing times due to longer TLS handshake

We are investigating the root cause and mitigation options.

Updates

Watching

Mitigation actions were taken and latency decreased for the impacted reverse proxies starting at 10:00 UTC. It has returned to expected levels on all reverse proxies since 10:11 UTC. We keep monitoring the situation.

Fixed

Metrics regarding TLS handshake latency are stable since 10:11 UTC. The incident is now over.
