Description

During update testing on dublin, I had an instance enter its reincarnation cooldown (currently 1 hour) through no fault of its own:

  • Initially running on sled 17 (had been up for many hours)
  • Sled is rebooted for an update; instance is marked as failed when the sled comes back
  • Instance is immediately restarted, but placed back on sled 17. It fails due to #9095.
  • The instance is now penalized for failing too quickly after start, and must wait for the cooldown to be restarted again.

Research direction

Start by tracing the instance reincarnation cooldown logic and the failure path described in this issue, then compare the related failure in #9095. Done means failures caused by sled reboot/update handling or that reported fault do not trigger the cooldown, while genuine rapid-start failures still do.
