Gee, my provider uses Ciscos and they're doing "maintenance" on them like once a month. Software upgrade or not...if you bring it down, it ain't up "for years", and I cant imagine anyone still using the crap that cisco was selling 4 years ago without upgrading..... > >In general, moving parts mean lower reliability.

Fans on processors? With REAL MTBFs in the >single-digit-thousand hour ranges? Yeah, right. For someone whos rich and idealistic, yeah :-). I'll bet that if you asked 100 people if they'd deal with a crash every 8 or 9 months to save $10,000 on a box they'd go for it 98 to 2, and we know who 1 of those 2 would be..... Dennis
