The company I work for, can and do provide diverse circuits, but they
won't guarentee diversity between that and one of a different provider,
the reasoning behind this is, that one cannot know if/when the other
provider reroute their circuit, so that there is no diversity any more.

SDH/Sonet protection removes quite a bit of the problem yes, but often
it's usefull to get 2 circuits with diverse routing (and without
protection) instead of a single with protection, and the price is 
usually in the same order for both.

We always get multiple circuits with diverse routing instead of a single
circuit with protection if we can.
