Between approximately 1:50-7:43 AM US Pacific time on 14 April, almost all Airship services were unavailable. This occurred because our domain registration for urbanairship.com expired even though current evidence indicates that it was set up correctly to renew automatically. Airship engineers were made aware of the issue by internal monitoring when it began and immediately began working to restore services. After the critical impacts resolved, intermittent DNS errors continued to impact customers' ability to log into our go.urbanairship.com web dashboard (though go.airship.com and go.airship.eu were available) or use our go.urbanairship.com APIs in some locations for a further 24-48 hours. We have completed a Root Cause Analysis that is available via our Support team, are pursuing an investigation with our domain hosting provider to see why the auto-renew was not executed, and have identified investments to prevent any future recurrence of this magnitude. We sincerely apologize for any inconvenience this may have caused.
