Stytch - Elevated error rate in API – Incident details

During Cloudflare's 2025-11-18 incident, Stytch's services continued to operate as normal.

However Stytch customers that use Cloudflare in their own infrastructure may have seen their requests to Stytch, either client or server side requests, fail to make it to the Stytch API, thus causing their auth flows to fail.

Though the Cloudflare incident did not cause any downtime in Stytch services, due to the popularity of Cloudflare, we've created this incident for posterity for customers investigating downtime in their own systems.

Services are recovering in the upstream provider, Cloudflare. Customers may continue to observe higher-than-normal error rates if they utilized Cloudflare in the meantime.
