oh we have spare FRU's for just about if not everything, but the 2x$ for not having to swap something usually isn't there. we tend to be more like an ISP/Colo/Support rather than actual provider (there's nothing stoping anyone from spending the $ if the do need the reliablilty). they get what they're willing to pay for.

mail, dns, and the like are trival to failover somewhere. CPU board won't boot, yank it and let the others take the slack. CRITICAL wierdness, the top level Vendor support will be on the phone in minutes and on site in person with replacement in hours if needed. i've seen it happen more than once.

much worse is when the machine running jobs that take 6 months to over a year to complete has issues. or problems with backup generator (3 days)/power or airconditioning which could comprimise everything. or heaven forbid the metro gigapop burns to the ground ;-). much more troublesome than a 30 minute disruption in something like mail/web/oracle type of failure.

i think i'm trying to say that we spend most of our money on the facility/research/infrastructure side and the application side of things is limited by what the customer (other deparments) is willing to pay for.

or maybe that your dual-everything transparent failover everything will get you naught if somewhere down the line both of your redundant feeds cross through the same manhole over which a gasoline tanker truck has just exploded and your fibers are being fused into a multicolor blob. (much more likely to be a backhoe digging where it shouldn't be digging or rats which have a sweet tooth for fiber cladding). but i ramble...
