There was a high-severity incident on the Canadian servers at approximately 8:09am MST that affected some clients' ability to log into their WaitWell staff app. The log in challenges were intermittent. The incident was resolved by 10:15am MST. The cause of the incident was an unresponsive caching service we use to maximize database performance. This service would typically failover to its backup servers during an incident, which didn't occur in this case. We're putting corrective measures in place. This was NOT a security nor data related incident.
