how many providers have multiple POP's in a city that are _completely
redundant_?  That is, they can operate _fully_ with one POP out of
service?

none can operate *fully*, as a customer access line pretty much has to
terminate in a single router which can, and eventually will, fail.

but, most large providers have more than one pop in the largest cities,
bay area, nyc, dee cee, etc.  and those pops are redundantly and diversely
wired.  if not, don't buy from them.  life can be simple.

of course, in toledo, you're probably sol.
