We are going to upgrade fileserver “peck” on Friday June 19th 2026. The plan is to do it early in the morning, but you may experience some issues after the upgrade as well. Rebooting the client computer may solve the problem in that case. Please keep an eye on this page to check whether the upgrade is completed or not. The upgrade was finished, but it took a bit longer than expected. ...
After a scheduled reboot of the machine running jupyterhub, jupyter failed to start properly. The service started after invoking a manual start command. The measures taken to resolve this recurring problem have not proven to be sufficient.
Due to a misconfiguration of the DNS in the z.science.ru.nl zone, all shares were not available during the outage. Extra tests are added to prevent a future occurrence.
The router for most Science services urgently needs a reboot. This has been scheduled for early morning. In the unlikely case that this reboot fails, ILS Connectivity is on campus to fix it.
In preparation of the migration to Microsoft Exchange Online Protection (MS EOP), we added another mail exchange server (mx5) to be addressed directly by MS EOP. However, having had mx4 in production for some time, we forgot to test mx5 in conjunction with our mailman server (zaaivm). This could result in a bounced mail ’not accepting messages’ for FNWI users (employees and students) using @ru.nl addresses. Meanwhile, mx5 has been made known to zaaivm thus resolving this issue.

The poster printer kamerbreed was broken. It couldn’t be fixed, so we ordered a new HP Designjet Z6 44 inch postscript. The ordering and delivery took way too long, the new poster printer was in operation on November 13. The new printer is twice as fast, so the speed of service will be even better. When our poster printer breaks down, users that need posters can go to Radboud Post&Print.
For an unknown reason, the Jupiter and Chemotion servers didn’t start. We are currently looking at how we can start the machine again. The virtual machines have been rebuild, based on their existing disks.

A combination of factors causes this to affect performance, fullness, uneven distribution of data over the storage nodes. We expect this to be resolved when the node is back in the cluster. update 7 Oct 2023 The cluster is mostly complete again for a while already, but there’s a lot of remaining issues to be resolved by the cluster. Performance may or may not be affected…
The RU contract with the anti-SPAM/anti-phishing service Proofpoint expired September 21, 2023, which means that ‘Proofpoint End User Digest’ mails are not sent anymore after that date. C&CZ is migrating Science mailboxes to the anti-SPAM/anti-phishing service of Microsoft Exchange Online Protection. There is an increased chance of receiving SPAM/phishing mails in the Science mailbox during this migration period. P.S. the RU central mailboxes (with addresses ending in @ru.nl) have already been migrated to Microsoft Exchange Online Protection. ...
