API outage

Incident Report for Tipser

Resolved

On Thursday, September 15, 2022, between 19:50 and 20:10 UTC our APIs became unavailable, as HTTP clients were unable to verify a TLS certificate securing a connection to our endpoint.

It was a transient incident caused by our CDN provider:

"On Thursday, September 15, 2022 at 17:44 UTC, Fastly deployed a configuration change to how fallback entries in our TLS configurations are generated. This led to incorrect intermediate certificates being referenced in non-fallback entries. This would have resulted in 5XX errors referencing inability to fetch local issuer certificate. This change was reverted, mitigating the incident.”
