RE: circuit routing to avoid network outages We at BBN Communications are sometimes asked by commercial customers to specify sufficiently redundant circuits such that the built-in adaptive routing of the backbone won't be undermined by any single telco outage. In one particluar case, the customer went so far as to request a hard breakdown of the *SATELLITE* and transponder each circuit used and of course the various earth stations. They were apparently worried about killer asteroids. Access to this info is of varying difficulty. However, this is serious business and many are willing to pay the delta. Q: What to do when ALL international circuits to a given country pass through a single point? e.g. Caracas, CANTV Central Switch A: Get a license from that country to put in your own earth station! (This is no longer a small delta although VSATs are coming down.)
