It's not uncommon at all to have a single interconnect between providers in
a geographical area. Multiple interconnects within a region tended to be
more for load balancing, not redundancy.
There have been certain providers that, historically, could or would not
support anything larger than an OC48. In those cases you had multiple
circuits to maintain traffic balance. When they finally migrate to 10GE you
back off to a single circuit and use your backbone for city redundacy.
