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.

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.

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.

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.

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.

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.

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.

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.

Update 07:25 The migration is complete and our mail server is back online. Please let us know if you notice anything peculiar. This concludes our multi-step migration to the new mail server hardware

In order to finalize the upgrade of the D-PHYS mail server, we schedule a maintenance downtime on

Tuesday, March 27, between 06:30 and 08:00 in the morning

During that time it will not be possible to send or receive emails. In particular, incoming external emails will not be lost, but held on the sender’s side and will be delivered after the migration. Outgoing mail will be kept in your mail client until the connection is restored.

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

New location for mail filtering rules, forwarding and vacation auto-replies

After the migration, all mail-related settings will be consolidated into the Roundcube Webmail interface:

• spam filtering rules (whitelist, blacklist)
• forwarding of your emails to a different account
• setting a vacation or out-of-office auto-reply message
• defining rules to automatically file incoming mails into specific folders

This will make configuring your email settings easier and also give you more options than before (for example, the out-of-office auto-reply can now be configured to automatically terminate at the end of your absence).

Please refer to our readme for details on how to customize these settings in the future. Feel free to contact us if you have any questions.

The current settings of all active users have been converted and imported.

In technical terms we are migrating from procmail to sieve. In particular the hidden text file ~/.procmailrc in the user's home folder will be ignored after the migration.

Update 07:25 Migration finished, welcome on the new mail server!

We schedule a maintenance downtime for the D-PHYS mail server on

Wednesday, January 24, between 07:00 and 08:00 in the morning

During this period, sending and receiving new emails will have interruptions, thereby delaying incoming and outgoing mails. In particular, incoming external emails will not be lost, but held on the sender's side and will be delivered after the migration. Outgoing mail will be kept in your mail client until the connection is restored. The IMAP server will not be affected, so all email clients should have continuous access to the existing mailboxes.

This maintenance window will be used to migrate the first part of our mail server infrastructure to the latest version of the operating system and new hardware with fast SSD storage.

New location for SpamAssassin user preferences

We re-designed how our mail server is parsing the user's configuration for the spam filtering. Currently one has to edit the hidden text file ~/.spamassassin/user_prefs in the home folder. Starting from next Wednesday the spam filtering rules can be edited more conveniently through the settings in the Webmail interface. This will allow users to easily

• accept mail from a given sender and never mark it as spam (whitelist)
• reject mail from a given sender and always mark it as spam (blacklist)
• set the threshold score required for any message to be considered as spam

The existing user preferences have been parsed and all of the above settings have been imported into the new setup. The contents of ~/.spamassassin/ will be ignored after the migration. Please contact us if you have questions regarding your advanced SpamAssassin rules.
