I think it's likely that he gets denied a connection when he is home
(outside working hours) and then allowed SSH connections when the sysadmins
are in duty. This prevents the possible accumulation of zombies, at least
assuming that you have entire clusters with high bandwidth backbones. It is
worth finding out if there are restrictions based on hours. The OP knows
better when he attempted to connect remotely, so can make better judgement.
