ISY Portal has been down last night for about 1 hours and 30 minutes, starting 2022-11-30 03:50 UTC (22h50 Eastern time, 19h50 Pacific time).

This was caused by a performance problem with the database server. The root cause was a performance problem on a specific query related to oAuth services and it was resolved by adding an index. The problem appeared suddenly because the queries were taking longer and longer and reached a threshold where Alexa services were resending requests, creating deadlocks.

The service was restored around 2022-11-30 05:10 UTC. 

During the outage, access to Portal services were prevented, including Alexa and Google Home services. After service restauration, Alexa, Google home and other services worked again.

During this outage, your Alexa skill link may have become "expired".  If so, please relink the skill.
