In reply to Only a hill: So can climbing. It's a calculated risk.
My last tent I owed failed in the cairngorms last febuary, worst conditions I have ever camped in, wind maybe 80 mph. Pole snapped about midnight. Calmly exited the tent before the effect of losing one pole snapped all the others, removed the poles from the tent, got back in tent, had a reasonable night's sleep.
Learnt from it as well. Snow wall should be substantially higher than the tent. Guys should be tied rather than relying on the sliders, as when the guys freeze and ice up, they slip. Bring lots of plastic bags for anchors, rather than having to bury all the ice screws, as that way you can leave the tent up when you're away climbing.
It was also practice for a similar situation, should it occur, in places where rescue/retreat may be impossible.
Also had a memorable incident on the cairngorm plateau, in summertime, got windy in the night, the sound of the tent ripping wasn't exactly what you want to wake up to.
Both were pretty old tents, that I picked up for almost nothing.
