Service Interruptions


1407: NFS problems under investigation

When we moved the gateways of our networks from the old location to the new firewalls, we have received some complaints about NFS filesystems having slowness, longer delays or unavailability. In general NFS should never be a requirement for a clusternode job if you can avoid it, because this I/O is always much slower than local I/O from /scratch. We are investigating how we can optimise the network to resolve this issue, but we are hard pressed to know the exact cause of the problem....

1415: Clusternode maintenance day - February 6th 2026

Every half year we do clusternode maintenance, with at least a package ugprade and a reboot, but sometimes other maintenance can happen, such as changes in filesystems or network configurations. The upcoming date for this maintenance is February 6th, 2026 (Friday)

1417: Network changes websites

To make the network less complicated and more easily manageable, we need to make vlans for the subnets 131.174.8.0/24 and 131.174.9.0/24, this will involve some servers getting a new ip address. This affects firewall rules as well. We must coordinate this with ILS networking and the changes will cause disruptions between a few minutes up to a quarter of an hour.

1148: RU Internet connection down for maintenance

The ISC has announced that on Tuesday morning, October 20, 2015 between 00:00 and 03:00 SURFnet and the ISC will perform maintenance on the connection of the RU with SURFnet/Internet.

1145: Radboudumc buildings power switched off for test

Wednesday September 30, around 4:00 p.m., Radboudumc will carry out a test by switching off the power to almost all their buildings. For the RU buildings this test has no direct effect. Liander states that switching off and on again will have no noticeable effect on the rest of the power net in Nijmegen including Radboud University. However, switching high power always has the possibility of introducing a power problem elsewhere....

Saturday September 12, between 9:00 a.m. and 1:00 p.m., maintenance work will be conducted on the network router at the Faculty of Science and a number of server switches in C&CZ data centers. This means that between these points in time, a few brief network interruptions with a duration of approximately 1 minute will occur. Many FNWI servers will be unreachable at those moments. The Mitel IP phones will also go out of service momentarily several times....

1143: Mailman mailing list problem

This morning we came to know that mails to mailing lists were not accepted by the mailing list server. The reason was a change that was made last Friday because of the new smtp server mid July. After correcting the change, mails were accepted again.

1141: Water damage for pr-hg-03-825

A leak above the KM MFP hg PR-03-825 made this fail beyond repair. We hope to resolve this by replacing it by a little-used KM MFP of the same type.
