Unfortunately the issues at the German datacenter have resurfaced, with customers experiencing some delays with inbound mail.  To address this as quickly as possible, we have diverted almost all traffic away from the German datacenter.  Those changes have already begun to take affect and should be fully propagated within the next few hours.  We expect that should solve the problem for customers, while our engineering team works on isolating and remediating the root cause.

Thank you for the patience as we work on this issue.
