The MTBUSWA Interval
Pete Ehlke and Steve Barnet write :
This is a most interesting phenomenon.
I have named the number which seems to describe it as MTBUSWA: Mean Time Before Users Start Walking Around (ASR denizens should make the obvious L expansion as appropriate). This number represents the interval between a network entering the hosed state and [l]users entering the confused-asking-other-users-if-they-can-reach-the-network state.
Typically, this interval seems to be under 2 minutes, but varies from system to system. This is followed by the lusers entering the asking-the-admin-if-(s)he-knows-the-network-is-hosed state.
Which is followed by the lusers entering the trying-to-log-in-every-10-seconds-until-it-works-state.
Which is followed by the immediately-call-the-sysadmin-because-the-NFS-volumes-aren't-there-yet state.
