There is another thing - if you are multi-homed, and want to switch providers, it is pretty seamless and painless - no renumbering, no
loss of connection, etc., as you always have a redundant path.

of my redundant links via 100% Fiber network. Even though this is
cheaper for me, all it takes is for AT&T to have some major outage and I
will be screwed. If I have a backup fiber line from say, Global
Crossing, then it doesn't matter if AT&T takes a nose dive, I still have
my redundancy there.
Well, I think this, in many cases, boils down to being able to pick the right provider.
I mean, some providers go belly-up from time to time. Others are designed/run better.
For a major provider, complete outage of all of its customers is such a big thing they'll want to avoid it always. If it happens, for a brief moment, once in five years (for example), for most companies that's an acceptable level of risk.
