Where do your 911 fees go and why does 911 fail

Yeah there wasn't a lack of options for fail over. I suspect there was a
lack of care to plan or test for them by many parties. Regardless, I
personally have backed off really blaming bell for this one other than the
cell towers going down. If you can't happily lose a campus for a week, it's
the design that's the issue, not the non infinite uptime of the campus.
