Our logs show the incident started on 5/18, 13:00 EDT and that during the 7 hours that it took to resolve the issue customers using Diagnostic Settings to export logs and metrics to Log Analytics would have experienced data loss/gaps in their Log Analytics workspaces during this time. Due to this customers may have also experienced false and missed alerts.
