RE: TransAtlantic Cable Break

["Rod Beck" <Rod.Beck () hiberniaatlantic com>]

Protected 10 gig waves NYC/London are extremely expensive. Say $60K or more per month. 

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 ...

Is paying for "protected circuits" actually worth it.  Or are you better 
off just buying two circuits and using both during normal conditions. 
Use switching at layer 3 to the remaining circuit during abnormal 
conditions.  Most of the time, you get twice the capacity for only twice
the price instead of a "protected circuit" where you only get the once 
the capacity for twice the price.

Of course, there is still the problem some facility provider will "groom" 
both your circuits on to the same cable.  If you are buying pre-emptable 
circuits, hopefully you understand what that means.
