In order to perform system-level maintenance work, we schedule a maintenance downtime of the D-PHYS mail server today (Thursday, 2nd of July 2015) starting at 17:00. We expect the downtime to take about one hour.
During the downtime all mail services (sending mail, receiving mail, accessing mailboxes, webmail, etc.) will be unavailable. Mails sent to D-PHYS users during the downtime will be held back on the sending side and will be delivered after the downtime.
We will post an update as soon as mail services are back.
Update 19:30: Took a little bit longer than expected, but everything is back to normal now.
