Monday evening October 1, there will be maintenance on central RU network equipment: all routers get a software upgrade. From 22:00 hours, parts of the RU network will not be available, a.o. wireless and Internet access. The network in Huygens and other FNWI buildings will not be available from 01:00-02:00 hours. Also C&CZ services will be disrupted. Please think which processes depend on connectivity to RU central services and prepare for this possible outage if necessary. Future maintenance windows can be seen on the ISC website.
