[Resolved] Connectivity Issues

In the early hours of 12-Aug-2018 (CEST) we had some connectivity issues that affected a number of our services such as IMAP, POP and the webmail. The issues were resolved by restarting a server that was unresponsive, and further investigations will be carried out in the coming days to see if there is an underlying cause that we need to deal with. Apologies for the inconvenience.
