to 'do an msn server' is to not work when needed. It is to piss everyone off when it is inconvenient for them. It is also to respond slow and do maintenance or repair at the completely wrong time and without warning
Billy: Man... those road works are totally doing an MSN Server!!
Bobfred: Yeah I know... i needed to get to work down the main road which is only 2km, but i had to go the long way, 10km instead!
