We've got a random sampling of people across campus (in different buildings) whose networking didn't work at all this morning. Reboots and other fiddling didn't work - and then they all just started working around quarter till nine. There is nothing posted on Service Status, but there appears to have been a problem with DHCP. Doing a reboot or DHCP Release/Renew now works. Is anyone else seeing this?
