Because of a software upgrade of the network switches in the buildings/floors/locations mentioned above, these network switches will be rebooted at 06:00h (AM) exactly. This means that both wired en wireless networks at these locations will be interrupted for 10 to 15 minutes and network traffic will not be possible. This includes the network for access control, climate control etc.
After the network maintenance of 20141111 a single user reported later a problem with the wired network. These problems intensified and grew faculty wide on 20141119 at 13:34 hours. The network switches in the Faculty of Science received so many topology changes of the Spanning Tree Protocol (STP) that network traffic often stuttered. By curbing the STP traffic on 20141120 at 15:32 the stuttering disappeared. We still search for the exact cause, probably it is a housing move....

Because of an upgrade of the network switches in the buildings/floors/locations mentioned above, these network switches will be replaced. This means that both wired en wireless networks at these locations will be interrupted and network traffic will not be possible. This includes the network for access control, climate control etc.
Due to a short DDOS-attack the RU was virtually disconnected from the Internet during ca 7 minutes. All network connected systems may have had problems during that time. Until 15:30 some Eduroam users still had problems acquiring an IP address.
The router that regulates all IP traffic between subnets in the Huygens building and surrounding buildings, became too busy. All network traffic, especially UDP had problems. ISC network admins reduced the load by simplifying the ACLs and reducing logging. At about 12:00 the problem was temporarily solved. C&CZ will do a further inspection of all ACLs, with the aim to reduce the load on the router without reducing security for connected systems....
On the ISC website we read: Radboud University agreed on a new mobile telephone contract with - again - provider Vodafone. For this purpose, on Wednesday, September 24th during daytime the Radboud subscriptions will be adjusted. Employees with a Vodafone mobile wille have no disturbance in calling or being called that day. But the Vodafone data network might be temporarily unavailable. To restore the data connection it is necessary to turn the mobile phone off and then on again....
The server that acts within FNWI as first DNS resolver crashed. This made the network virtually unusable for a lot of computers in FNWI. Only after a reboot of the server, the problem was solved. Measures to reduce the inconvenience of such a crash and to make such a crash less likely, have been partly taken and are partly in preparation.
A defective disk made the server stop serving web requests. A reboot fixed the problem. The defective disk will be replaced soon.
