Root cause has been isolated to a backend component becoming overloaded with an unexpectedly large number of alerts which was impacting the ability to process new alerts. To address this issue we have found the alerts generating a large quantity of noise and have removed them and scaled up the backend service to handle the backlog. The backlog is currently draining, alerts will continue to be impacted until we can complete this process.
