We are currently experiencing severe issues with accessing your home directory from machines at Ullevål. This is causing most machines, especially our Linux hosts, to hang. We are working on resolving the issue.
Update, 2018-03-27, 07:47: Last night the primary connection between our server room and the rest of UiO (and thus, Ullevål) was first found to cause errors. Traffic is now routed through a redundant link and things appear stable.
Update, 2018-03-27, 11:40: An SFP+ module for UiOs fiber infrastructure was found to be at fault. It has been replaced and thing are back to normal. Apologies for the disturbance.
