SLAs for colo sites?

[hank at efes.iucc.ac.il (Hank Nussbacher)]

A neutral colo site has to just provide two things really: A/C and 
power.  What happens when a colo site loses power even though they have all 
the necessary bells and whistles - generators, UPSs, multiple electrical 
carrier feeds, etc.  Can anyone point me at actual online SLAs for colo 
sites that not only state 100% uptime but also state what happens if they 
fail that promise?

Thanks,
Hank
