PingID stopped functioning correctly which prevented users from being able perform second factor authentication. The root cause of the outage was a data replication failure in the session management system. An unusual circumstance occurred where a failed node was replaced then rebalancing of session data stalled the entire system. Mitigation actions were taken and the system functionality was restored (see below).
North America customers were not able to utilize PingID during the duration of the outage. Some customers may have experienced a broader outage depending on their specific configuration affecting users outside of North America.
Restarting the web services allowed the stateless session management system to fully recover.
