The server had a high load and stopped servicing users, probably because of problems with the creation of new snapshots at 13:00 hours. A reboot solved the problem.

On Monday evening, February 3rd between 19:00 - 24:00 (7:00 - 12:00 pm) maintanance will be carried out on the network devices in Huygens Wing 5. Therefore the wired and wireless networks will not be available at some moments at all locations in this Wing, on all floors.

The announced proceedings on Tuesday, January 21st on the network equipment unfortunately did not take place due to a sudden instability of the network in Wing 1 the same day. In order to prevent further instability issues in Wing 2, it was necessary to solve the problems in Wing 1 first. These problems have been identified and corrected. The network maintenance in Wing 2 will now take place Tuesday, January 28th between 19:00 and 24:00 ( 7:00 pm to 12:00 ) during which the wireless and cabled networks will be off line for some time. This will affect all floors in Wing 2 and rooms along the corridors between wings 2 and 4 (all floors).

On Tuesday evening January 21 between 7:00 pm and 12:00 pm maintanance will be carried out on the network devices in Huygens wing 2. Therefore the wired and wireless networks will not be available at some moments at all locations in wing 2 and corridors between wings 2 and 4, on all floors.

On Monday evening January 13 between 7:00 pm and 12:00 pm maintanance will be carried out on the network devices in Huygens wing 1. Therefore the wired and wireless networks will not be available at some moments in many locations in wing 1 and corridors between wings 1 and 3, on all floors.

Due to an error by an ISC network administrator, all internal and external RU network traffic was blocked for a short period.

The replacement of the old home server “bundle” has been postponed and will now guaranteed take place on Monday morning December 23. Because the data have been synchronized with the new server, there will not be much downtime. The new server should be very dependable: hardware RAID-6, double processors and power supplies and a 5-year support contract from the supplier. The performance has improved, e.g. by using hardware RAID with a 1 GB write cache with battery backup.

In the course of these two days, above network shares will be moved to new servers. During the move action, a share will not be available. If you encounter any problems connecting to a network share using Windows, always connect using the “share-name minus srv” naming scheme: \\sharenaam-srv.science.ru.nl\sharenaam.

Tuesday night December 17 19:00-24:00 hours, maintenance work will be done affecting the data network in Huygens wing 1. The wired and wireless network will suffer service interruptions a few times during that period. The main inconvenience will be on the ground floor.

C&CZ changed the DHCP-configuration of the KM MFP’s, because KM had told us all KM’s had an identical configuration after the upgrade of the night of December 4. Soon thereafter the KM’s outside of the Huygens building showed problems. After changing the DHCP-configuration back to the previous version and restarting the MFP’s, the problem was resolved. The firmware upgrade of these machines still has to take place.
