I think that's the main reason why the news media -- particularly the
big national news shows -- have concentrated on NYC. Nothing to do
w/ 9/11, IMO, but more to do with the fact that they all have their
offices there, their offices have backup generators, and
communications with other cities are limited.

It has to do with how the interconnects are set up. NY State, Ohio,
and several Canadian provinces are in one region; most of NJ,
Pennsylvania, Maryland, and DC (where I live) are in another. The
different regions are all interconnected, as well, but there is a
system that disconnects one region from the others at the first sign
of trouble. In fact, the local electrical people here in DC have
been on TV gloating about how well their system worked, since
apparently it did immediately disconnect from the NY system.
Clearly, though, a system that protects different cities within the
individual regions is needed.
It is ridiculous that the entire region went down. There is simply
no type of power plant equipment failure that could affect such a
large region, which requires hundreds of plants to supply it. I'm
guessing there was some sort of computer system failure, or else
someone or something triggered a small shutdown, and the entire
transmission switching network is just so messed up, or old, that it
completely malfunctioned. The latter, as I understand it, is
essentially what happened in the big NYC blackout in 1965, but you'd
think that someone would have solved that problem in the intervening
38 years.

A backup system for the entire network of traffic signals would be
extremely costly. There are just so many traffic signals spread over
such a wide area -- it would be a lot more difficult and expensive
than, say, buying a small backup generator for a small business.
Would it really make sense for the gov't to spend millions on backup
systems for traffic signals for such a rare event? It's considerably
cheaper just to pay a few hundred cops overtime to go direct traffic
at the main intersections.
