Hardware failure on mail server

Thursday, August 27th, 2020

Update 09:45: the mail server could be recovered. It'll take some time for all queued incoming mail to be delivered.

Early this morning, a RAID controller in the D-PHYS mail server died. We're trying to get replacement parts later today. In the meantime, there's no access to email.
We apologize for the inconvenience.

The Informatikdienste are upgrading the routers in our HIT/D/13 server room causing a downtime of the network of about 1 hour on Thursday morning, 15th September, between 05:30 and 07:30. Please note that various services will not be available during that time.

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.

Short-term maintenance downtime

Monday, February 2nd, 2015

UPDATE 23:00 - maintenance finished, queued mails have been delivered.

As a probable aftermath of last week's power outage we are experiencing some issues with the file system on our home directory server which can only be repaired offline. We therefore schedule a maintenance window

Today, Monday Feb 2, 2015, starting at 22:00

The duration of the downtime cannot be estimated but should not exceed two hours. During this time you will not be able to access your home folder or receive new D-PHYS email. All incoming mail will be queued for later processing.

Thank you for your understanding.

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.

Please note that the whole HIT building will be without electric power during this time (The server room HIT D 13 is excluded from this interruption).

ISG Helpdesk Service Interruption – Reprise

Tuesday, February 12th, 2013

Apparently this time they mean it:

On Thursday, February 14, ETH facility services will conduct extensive power network tests in the HPT building, where ISG (and hence the helpdesk) is located. Power will be gone for ~ 2 hours starting around 13:30. During this time we will not be able to answer the helpdesk phone or work on your tickets. We'll post an update when power is back.

Update, 10:30h: We're already offline since in other floors of the building power has already been cut and caused a network outage on other floors.
