EU: feature flags and surveys with elevated error rates

Incident Report for PostHog

Resolved

EU: We were observing increased error rates for feature flags and surveys.

While mitigating first issues with feature flags, we were restarting some internal components, which caused other issues.

Surveys showed elevated error rates between ~15:22 UTC and 15:36 UTC.
Feature flags showed elevated error rates between ~15:00 UTC and 15:36 UTC.

There was a large number of timeouts in our database in the EU region causing high feature flags error rate and service disruptions.

Apologies for this disruption.
