[Monitoring] Email access and deliverability issues

We are currently experiencing issues with delays on email access and delivery of incoming email and are investigating what’s causing these. Indications thus far point to a possible attack on our services.

We apologize for any inconvenience caused while we work to resolve these issues.

The situation is normalizing and both email access and email delivery should be normalizing as well. The cause of the problems appears to partially have been a substantial influx of spam that resulted in delays in spam scanning and subsequently email delivery.

Investigations indicate that a exacerbating cause is brute force attacks from a large number of IP addresses. We are implementing measures that are successfully countering these attacks to further improve the response and delivery times of our services.
