Ah, servers going down like the Titanic...
I remember of my dear old mates who, at the time, worked at a nearby university in the IT admin department. Anyway, long story short, coming up to the end of the calendar year, nothing major going on, and they were having their Christmas meal that evening (I'd bagged a +1 - go me). So, in the spirit of the season, they wound down for the day early, cracked open a couple of beers, and may have even managed to sneak in some fine smoked "oregano".
It must have been at this point that EVERY LECTURER decided to release their January exam timetables online, as for some reason, the students gave the uni servers the Hug of Death. I'm talking 95%+ student logins, in a rather large uni.
Right as my friend was putting his coat on to head down to the restaurant, he cast a glance over his shoulder and spotted a rather large red spike on his screen, coupled with lots of flashing red lights.
Needless to say, that was an "interesting" afternoon. I ended up getting drafted in to do some reboots and whatnot. Must say, there was a great soundtrack of UB40 in the background.
And that's my somewhat relevant story.
