KoalaSafe experienced a outage on one of its API servers from 06/05/2018 22:18 - 07/05/2018 1:42 UTC
The issue was caused by automatic security updates being applied. The health checks that ensure updates don’t effect the application were insufficient and the updates were not rolled back resulting in the API being unavailable for users who were assigned to this server.
The health checks and alarms for this scenario have been improved.
