PASSPORT · WHAT THIS ROOM DID

Why does the same outage keep recurring?

Every line is from the record. Nothing is computed for this page, and nothing is smoothed: a short list of disagreements means a room that agreed, not a room whose disagreements were tidied away.

What it rests on
  • The service map in the wiki is two years old
  • One engineer knows how the payment path actually works
  • Feature flags are never cleaned up, so nobody knows which paths are live
  • The on-call rota has the same two people on it most weeks
  • Rollbacks take longer than the outage they are meant to end
  • Alerts fire so often that on-call mutes them
What it could not settle
Published as contested, never recorded as a no.
  • none: every pair the room reached was settled
What was predicted to follow
Written after the map settled. Nobody voted on it.
  • No production deploy after 14:00 on Fridays unless the on-call engineer agrees — expected: the same cause stops coming back once fixing it is in the sprint — due 23 Jan 2027
What the room would do
Each action judged against each root cause, at three quarters of the votes cast.
