Today, we experienced problems with alert notification delivery between midnight and 10am pacific time (4am to 2pm UTC).  During this time, alert notifications were generated and held in a queue prior to being dispatched.

The issue affected alert notifications using email, Webhook and PagerDuty, for all alerts generated during the affected window.
