Remember before people get bent out of shape, nobody can guarantee a 100% SLA uptime on any product. why you see 98% to 99% uptime guarantee, it's to make sure that the 1% of the time you crash and burn, that you can crash and burn and use that 1% to fix everything. it happens, things fail, it's the nature of the beast when you run a huge environment like SL, remember this is an active product in development since 2003, some of it is old and legacy and can not be easily redone.
