Some locations are just too cost prohibitive to multihome, but that really is a select few.
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.
