The SurfNET Videoconference information
The SURFnet videoconferencing system has been decommissioned long ago. For PDP meetings, see the instruction for direct Vidyo access at https://www.nikhef.nl/pdp/video/. Phone conferences can be used through GridPBX (pick either the Free Love room 85000, or ask for a room to be created on kvasir).
The CTB has its own wiki: see CT Wiki
