1and1 hosting server down again after two days up

The server at 1and1.com just locked up again. It's been two days and a few hours since the last crash. That's sooner than the average which is around three days between lockups. 1and1.com's management claims that this is normal for a linux server and won't repair or replace the server. Unless I've lost count this is the 30th crash since early February.
