Yesterday at ca. 15:52 a SURFnet core router crashed, taking down the RU Internet connection. At 16:09 the connection was restored. This was reported yesterday on a temporary SURFnet service interruptions page and on the ISC/CIM service interruptions page. Details can be found on the SURFnet Network Tickets mailing list.

As a result of a short network service interruption last night, there were some problems with obtaining ip addresses on the wireless network eduroam.

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. From 00:00 to 01:30 there is no connection. Between 01:30 and 03:00 short interruptions may occur. We advise to check which systems can be affected by this and if possible shift network activity to a different time slot. You also might think about systems with alerts via Internet. ...
In the morning of October 8, some KM MFPs will be switched, in order to have the faster/bigger machines at the locations where the print volume is te largest.

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. If research, education or any activity will be seriously hindered by a power problem, you might consider ending this activity in time or taking measures to guarantee continuity with emergency power and UPS. ...
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. All other phones, however, will continue to operate normally. The maintenance work is necessary to enable resumption of the IP telephony rollout at the Faculty of Science. For further information, please contact netmaster@science.ru.nl. ...
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.
