Web services downtime

Tuesday, January 19th, 2021

Update 07:00 All web services are back online.

Tomorrow Wednesday 2021-01-20 starting at 06:00 we will upgrade the server hardware hosting most of our web services. We expect them to be back by 08:00 at the latest.

Affected web services

The following services are unavailable during the downtime:

Our Debian, Ubuntu and Raspbian mirror as well as Grafana, InfluxDB and Webmail will not be affected.

We will not be able to send any status updates via our news blog or via our Matrix news and status rooms.

Hardware maintenance of storage front-end server igp-data.

Monday, November 30th, 2020

 Update 00:30:

All shares coming back online now. My sincerest apologies for the delay. And good night to all.

Update 22:40: We have run into hardware problems with one of the backends. The shares remain offline as we continue to diagnose it. A further update will be posted as soon as possible.

On Wednesday, 02 XII 2020, between 18:00 and 20:00, access to
igp-data shares will be interrupted for scheduled maintenance.
The shares need to be taken entirely offline for a network upgrade.
At the same time we will be adding more space to the underlying SAN.
This affects all shares on the igp-data storage gateway (ggl, pf and gsg).

Thank you for your patience, and kindest regards.

Hardware maintenance of storage front-end servers.

Thursday, July 30th, 2020

Update 23:50: we ran into severe problems and the migration took longer than expected. Everything is back online now. Sorry we’re late.


Planned maintenance will be taking place on all shared-storage front-end servers on Thursday, August 6th, starting at 17:00. The service will be down for approximately 2-3 hours. This post will be updated as soon as work is completed, were we to finish earlier than expected. We will be upgrading the network switch and replacing hardware in several machines.

All group shares will be affected, i.e. group-data, IPA, IGP and Galaxy. Only the home and backup servers will be accessible during this time.

For emergency cases, there will be read-only access to last night’s backup as described here.

Group-data server hardware maintenance.

Tuesday, June 16th, 2020

Update 18:15 group-data is back!

Planned maintenance will be taking place on our group-data.phys.ethz.ch server on Friday, June 19, starting at 17:00. The service will be down for approximately 2 hours. We will be replacing the network interface card to improve service stability.

All group shares will be affected except IPA, IGP and Galaxy.

For emergency cases, there will be read-only access to last night’s backup as described here.

Migration of Dynamic DNS

Tuesday, January 21st, 2020

Some of you make use of our DynDNS infrastructure that automatically assigns hostnames to computers with a dynamic IP address. This feature enables you to connect to your computer using its sent hostname, followed by the dhcp.phys.ethz.ch domain (eg example.dhcp.phys.ethz.ch) instead of the ever-changing dynamic IP address.

Thursday morning

Jan 30 2020 between 9:00 and 11:00

we will be migrating our DynDNS service to the servers of central Informatikdienste. As a consequence the resolution of example.dhcp.phys.ethz.ch to its dynamic IP address may not always work during that time. The global phys.ethz.ch and ethz.ch domains are not affected. Therefore the bulk of our users will not even notice the migration.

Update: Informatikdienste have postponed the migration from 23rd to 30th January.

Groupware upgrade

Wednesday, September 25th, 2019

Update 08:00: Migration completed. Please note that a legacy CalDAV URL has changed – if you’re using a CalDAV client (for example Thunderbird or Apple Calendar), make sure you have the correct URL according to the documentation

For our calendar solution groupware.phys we schedule a migration on Friday, September 27, starting at 07:30. The service will be down for approximately 1 hour. We will move the service to a new virtual machine and upgrade to a new version.

FileMaker Upgrade

Friday, August 30th, 2019

We will upgrade our FileMaker server next Tuesday 3rd September 2019 between 20:00 and 22:00 o’clock. This will lead to a downtime of the services that depend on a FileMaker database, for instance experimente.phys.ethz.ch and lager.phys.ethz.ch.

The new FileMaker server will only work with FileMaker clients version 16 or newer. If you need to access a FileMaker database from your computer, we recommend you install the latest FileMaker 18 from the IT Shop. If you have a ISG-managed computer, we will take care of upgrading the FileMaker client.

Home server maintenance on Tue, July 9, 17:00

Wednesday, July 3rd, 2019

Update 20:10 Migration finished! Everything should work as normal.

In order to guarantee sustained performance and availability of our storage system, we schedule a maintenance downtime of our home directory server on

Tuesday, July 09, starting at 17:00

This only affects the home shares (technically: smb:\\home.phys.ethz.ch & /home/USERNAME). Email and group shares will have no interruption.

Since the server also needs a file system check, the downtime will take several hours.

For emergency cases, there will be read-only access to last night’s backup as described here .

We will update this posting once the home server is back online.

Storage migration

Monday, December 3rd, 2018

Update 21:00 – IGP shares are back. Welcome to igp-data!
Update 19:30 – the D-PHYS shares are back. IGP will take a little more time.

In order to guarantee sustained performance and availability of our storage system, we need to schedule a few storage maintenance windows. The first one will take place on Wednesday, 12.12.2018 at 16:00 and affect all D-PHYS and IGP group shares, but not IPA or galaxy (technically: windata/macdata, but not astrogate or ipa-data). The relevant shares will be offline for at least 3 hours.

For emergency cases, there will be read-only access to last night’s backup as described here.

Please note that these migrations will bring some overall changes to the D-PHYS storage setup:

  • the SMBv1 protocol will be disabled on all file servers. It has a long history of security issues and we’ve migrated all clients to newer versions, so this should not affect anyone. However, there’s a small chance that we didn’t catch all connections, so please contact us if you experience any issues after the migration.
  • all SMB protocol versions will be restricted to ETH-internal access. This step has been long overdue and since most ISPs block the necessary ports anyway, it shouldn’t affect too many users. What it means however: in the future, file server access from outside ETH requires VPN.
  • IGP/D-BAUG will get their own front-end server igp-data. If you’re with IGP and have already switched your file server mounts from windata to igp-data, you’re good and don’t have to do anything. If you haven’t, you should do so before Dec 12 in order to get a seamless migration experience.

We’ll update this post as the migration progresses and as soon as the systems are back.

Groupware migration

Thursday, September 27th, 2018

On Tuesday, October 2, starting at 07:00, we will migrate our groupware instance to another server. For about 1 hour you won’t have access to your calendar. If you’re one of the few people who also sync their email via groupware, mail will be offline too (you can always use webmail). After the migration your clients should just reconnect and resume syncing. If you notice any issues after we’re done, please get in touch.

Update Wed 07:45: migration completed, please let us know if you experience any problems.
