Date / Time March 17, 2026 \~09:00 -- 14:30 Duration \~5.5 hours EST

Reported By Shane (Atlantis ITS) Assigned Shane + To Cooper (Coop)

Severity High Priority P1 --- Platform Rebuild

Environment Atlantis ITS --- AAL Platform Version AAL2 → Rolled Affected back to AAL1.5

2. INCIDENT SUMMARY

An upgrade from AAL1.5 to AAL2 failed, necessitating a full rollback. Due to an incomplete backup of the AAL1.5 state prior to the upgrade attempt, the rollback could not be performed cleanly from a snapshot.

  • Treat pre-upgrade backup as a mandatory gate, not an optional step
