|Affected||Users of Eduroam and Ru-guest|
At Monday May 19, a major upgrade of the wireless infrastructure and its maintenance tool (called Prime) will take place by the ISC. Therefore the wireless service (i.e. Eduroam) will be interrupted several times from 8:00 pm. Existing wireless connections will be lost and new connections will not be possible for some time. Due to the complexity of this operation this maintenance will possibly be continued at Monday, May 26, again with interruptions from 8:00 pm.
