On June 6th between 2:15am CEST and 2:35am CEST (5:15pm PT and 5:35pm PT, 12:15am UTC and 12:35am UTC) there was an increased rate of application errors on one of our Docker host instances in the US region. The instance is now fully operational and the jobs are safe to restart.
Furthermore one of our EU region Docker host instances went down at 6:56am CEST and caused a few unexpected application errors. There is a new one in place, we recommend restarting any failed jobs.
We're sorry for this inconvenience, we're working on preventing these errors in the future.
