The Wall Street Journal had an article Thursday about the problems
executives with large multi-national companies are having re-engineering
their telecommunication networks. None of this should come as a
surprise to long-time readers of any of the networking lists.
Just in Case, Many Firms Work to Set Up
Redundant Telecommunications Systems

John Smiley typically wears suits. But as the executive in charge of
telecommunications for Lufthansa Systems' North American operations, he
recently put on jeans and work boots to inch his way into a dirty train
tunnel beneath New York City's Grand Central Terminal.
His mission: to inspect new fiber-optic cables that snake through
abandoned gas pipes, ensuring that they are running on a safe, separate
path from a set of nearby fibers carrying the German airline's
I've done something similar in the past.
But it doesn't solve the problem. Even if the sales person promises
you diversity, even if you physically inspect every meter of fiber,
even if you pay more, after six months your network won't be diverse.
On a long-term basis, how do you check carriers are keeping their
promises? Are there any commercial products which let subscribers
automatically check DLR's from carriers for changes and conflicts?
Since DLR's only show the active components in a circuit, has anyone
developed a product to check for passive and location risks?
