Our Dashboard experienced a period of degraded performance early Sunday morning due to misconfiguration of automatic scaling in technology that is new to Pantheon. While customer web sites were not affected during this outage, Pantheon customers briefly lost the ability to make changes to their sites at the beginning of this incident.

We have conducted an internal review of the events that lead to this outage and developed a plan to allow us to prevent similar incidents in the future, detect degraded performance of our new technology, and recover more gracefully in the event of system failure. We are confident that our plan will effectively mitigate these issues.

We recognize that being able to change a site is as important as the site being available for use and apologize for any inconvenience caused by this outage.
