At this point all of the queued outbound notifications have been processed and are processing normally. Postmortem to follow.
POST-MORTEMMail servers in our West Coast data centre started processing less outbound email than was being created, leading to thousands of emails queuing up in. To clear the pending email queue, we worked to rearrange the number of servers dedicated to outbound email, including adding new services to the data centre.
We\\\'re still investigating to understand the root cause of this incident fully; however, as short-term remediation actions, we\\\'re working on increasing operational capacity of the West Coast data centre to prevent this or similar incidents from recurring.
