From the hours of 1:04pm UTC on Jan 20 to 8:19 am UTC today, Jan 21, we experienced an issue with individual alerts not displaying properly in the Web UI. This issue has since been resolved and new alerts are not affected. We are now processing a backlog of alerts which will appear under their corresponding incidents normally over the course of the next few hours. It should be noted that the Web UI was the only affected component and this did not impact our APIs, the mobile app, or notifications. This incident will be updated once we’ve finished processing these alerts.
