Our main database layer suffered a localized partial outage which affected various other components. The various components recovered once the main issue with the database layer was resolved and the accumulated backlog cleared up. There was no data loss and this was not a security breach. The impacted time duration was ~10m. We apologize for the experience and appreciate your patience during this incident.
