Email Delivery Issue: Between approximately 21:00 and 21:35 UTC, a very small subset of customer emails processed by mail tower T345 experienced a mail delivery issue. Email connections to this tower were presented with delivery errors. To remediate this issue, the impacted infrastructure has been taken out of service and there is no further customer impact. This issue is believed to be unrelated to the current mail delay issue.

Update

As of 19:15 UTC, we have taken half of the impacted US-East infrastructure out of service. This is to stop accepting any new emails and allow queued emails to deliver from US-East infrastructure.

Customers may continue to experience delays sending or receiving email. We will deliver queued email following our retry schedule once service is restored.

We will provide an update at 21:00 UTC or as soon as more information becomes available.
