Heh heh.. Ouch man, just pure ouch..

Yep, spot-on.  Their stuff spends 5 years in beta development before it 
hits the production mold.  These people try to break it in ways that we 
only wish would never happen to us.

They really do know their stuff and while I shake my fist at them for 
their black-box mentality and their closed-source EVERYTHING, I do have 
a LOT more respect for them making this stuff work as well as it does.  
Telecom is probably the last 5 9's tech left in the world.  Ever  thing 
about how long it would take to make * 99.999% available??  It hurts to 
just think about it.
