Server room migration on Wed, Aug 23

Tuesday, July 25th, 2017

Update Thursday 01:45: we hit some unexpected problems with the non-Astro group shares. Everything is back now, please let us know if you expericence any problems..

Some months ago, we were informed by Informatikdienste that we would have to migrate our two water cooled racks in the HIT server room due to upcoming remodeling. This move will take place on

Wednesday, August 23, starting at 16:00

and last for several hours. During this time, all our IT services will be unavailable, including login, e-mail, storage and ISG-hosted websites. Incoming e-mail will be kept back and delivered afterwards. We will give our best to have login and e-mail back up within the first two hours, but group drives will take a bit longer due to the sheer amount of hardware we have to move.
We apologize for any inconvenience. Unfortunately, this migration cannot be performed on a weekend as we might have to interact with our colleagues at Informatikdienste, but it will ensure secure and enduring operation of our servers in the future.

some impressions from the migration – thanks to the whole team!

Web server upgrade on Jan 19

Thursday, January 12th, 2017

On Thursday, January 19, starting at 08:00, we will OS upgrade the main D-PHYS web server. All websites hosted on zwoelfi*.ethz.ch will be down for several hours and will gradually come back as we progress. This does not affect the department website, the institutes and many of the group websites. However our groupware, the wikis and many special interest sites will be inaccessible. Note that if you’re using the ActiveSync connector via groupware to sync email to your cell phone or Outlook, this won’t work either. Temporarily use webmail while we bring back groupware as one of the first services.

Update 17:30 – due to an inordinate amount of user files on the web server the upgrade took a bit longer than anticipated. Now almost all websites should be back online, please let us know if you encounter any problems.

Tuesday, August 30th, 2016

In order to perform some core service upgrades, we schedule a server maintenance window on

Monday, September 5, starting at 17:00 and lasting for approximately 3 hours.

Most D-PHYS IT services will be affected by that downtime, including logins, file servers and e-mail services.
E-mails coming in during the downtime will be held on the sender’s side and will arrive at D-PHYS with a delay. Sending e-mails won’t be possible during the window.

We’ll update this posting as soon as things are back to normal.

Update Monday 18:30 We managed to complete the migration ahead of time, everything should be back to normal. If you still encounter any problems, please let us know.

Emergency Downtime of Mail Server

Wednesday, December 2nd, 2015

We had to shut down the D-PHYS mail server on short notice for replacing faulty hardware. Mail service should be back in the evening.

Mails sent to D-PHYS during the downtime will be on hold on the sending side.

Update, 19:30: The dust is settling. We’re soon back to normal.

Hardware Maintenance Downtime of Mail Server Today 5pm

Thursday, July 2nd, 2015

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.

Severe server failure

Wednesday, August 27th, 2014

sometimes it just has to work, and fast!

sometimes it just has to work, and fast!


UPDATE Thu 09:30 – all systems should be back to normal. Please let us know if you still encounter problems. Thanks to Axel and Paddy for their commitment and the incredible Dalco service for fixing it within 6h (at 8am, mind you).

UPDATE Thu 00:50 – a broken valve blocked the cooling water in the HIT D 13 server room and all 14 water cooled racks severely overheated (not just D-PHYS). We managed to revive almost all services with the exception of the GGL file shares (this server is dead). We’ll post updates later today when we have more information.

complete loss of cooling in the server room. We have yet to assess the damage.

Maintenance Downtime of D-PHYS Mail Server on 9-Jan-2014

Monday, January 6th, 2014

On Thursday, the 9th of January 2014, starting in the late afternoon, we will run multiple software updates on the D-PHYS mail server. We do expect multiple downtimes throughout the evening, partially of single mail services, partially of the whole mail server.

This will likely also delay the delivery of incoming mails up to several hours.

Update, 22:30: Everything back to normal.

General IT services downtime on Wed Sep 11 17:00

Tuesday, September 3rd, 2013

UPDATE Thu 12.09. 07:30 If you’re trying to connect to a SMB share from an unmanaged Windows machine, you have to use “ad\USERNAME” instead of just “USERNAME” from now on.

UPDATE 21:15 apart from the IGP group shares (which will be back in a few hours) all systems are back to normal. Please let us know if you experience any problems.

In order to upgrade the operating system on several core infrastructure servers of the Department, we schedule a general maintenance downtime on

Wednesday September 11, starting at 17:00, lasting for several hours.

Most services will be affected and unavailable during that time, as they require an authentication with your D-PHYS account (email, file server, print server, managed workstations). Note that, even though you will not be able to check your emails or send new ones, all incoming mails will be received and safely delivered to your inbox afterwards.

Please make sure to save all open documents before 17:00 on that day.

Since we will also change the way file server mounts are authenticated, users who haven’t updated their passwords in a very long time might not be able to mount their home directories or group shares after the migration. If you run into this problem on Thursday morning, please first change your password. If the issue persists, contact us.

We will post an update when things are back to normal.
