On October 8, 2018 Anaplan experienced a three minute service interruption from 14:50 PST to 14:53 PST at which time customers were unable to login to Anaplan.  The issue was caused by a service being active during a system restart and was restored by manually shutting down the service.  To avoid this type of interruption in the future, we have updated our processes to ensure all services have been shut down prior to a restart.
