It isn't just cost but can be path diversity (or lack thereof). We
used to be headquartered 210 miles from civilization. We had a
choice of providers and could have "multihomed". However, the only
realistic way for any of those providers to get to us would have been
Bell frame relay. Since by far the most likely point of failure was
the "last mile" (which was 210 miles), we made a decision that
actually multihoming wasn't a good use of resources. We instead went
with a good quality regional provider who was themselves multihomed.
Now clearly there were cases where that wouldn't have any good but
given the remoteness it just seems most likely that anything that
took out one provider would have taken the other one as well.
Now this case we are discussing is probably the exception to our
assumptions but we had a much better provider at the time than
Level3 ;-]
From the sounds of the original post I wouldn't be too surprised if
it was also fairly remote.
