Our operations team has observed unusual activity on certain servers. To ensure performance and availability, we will replace these with redundant systems. Once we start this brief 10-minute period of unplanned preventative maintenance, some restaurants may experience 5 to 10 minutes of offline mode. We apologize for this inconvenience, but prefer to do this preventative step now rather than risk any deterioration during dinner service hours. You will receive 3 more alert messages: 1 when we start the 10 minute maintenance, 2 when we complete the maintenance, and 3 when we have observed all clear normal operations for 30 minutes following completion.
