<BR>
So it usually makes sense for the Layer 3 guys to lease diversely routed 10 gig waves and do the protection themselves using MPLS or load balancing or some other protocol about which I know little ...<BR>

Is paying for "protected circuits" actually worth it. Or are you better<BR>
off just buying two circuits and using both during normal conditions.<BR>
Use switching at layer 3 to the remaining circuit during abnormal<BR>
conditions. Most of the time, you get twice the capacity for only twice<BR>
the price instead of a "protected circuit" where you only get the once<BR>
the capacity for twice the price.<BR>
<BR>
Of course, there is still the problem some facility provider will "groom"<BR>
both your circuits on to the same cable. If you are buying pre-emptable<BR>
circuits, hopefully you understand what that means.<BR>
