This really is way outside most people's "disaster recovery" scenarios. I can see the thinking now: "If both WTC towers fall over, we have much bigger things to worry about than fiber cuts." And they were right.

Right as far as that goes, yes. But since fiber paths of that kind are used to feed cell towers and other parts of the communications infrastructure including emergency services infrastructure, it IS worth thinking about communications robustness even in the face of destruction on this scale. Not so that folks can surf the web but so that folks in air pockets can call out to their rescuers. -- Paul Vixie <vixie@eng.paix.net> President, PAIX.Net Inc. (NASD:MFNX)
