Vulnerability of Telco Switching Equipment
call -151 writes: "Interesting New York times article about the Sept 11th attacks' effect
on the Verizon switches in lower Manhattan. Turns out there
was a problem in that much of the network switching was in one
building and it has taken a while to restore service. Sounds like there
is lots of pondering about the vulnerability of the network,
even when it is distributed across many physical locations.
Of course the attacks are making lots of people rethink their
vulnerabilities, but the estimate is for five years' work before there
could be redundant paths for the lines into their switches in
the one building, with no plans to spend the money to do it.
Maybe someone should send them a few hundred thousand 'self-install'
kits like they do with their DSL service ..."
So they are saying that if you take out a large telephone networks Central Office, people connected to this office will suffer lost connections. Infact some long distance connectivity will suffer as well.
Why does this suprise anyone. Hmmm let me see, if you take out your ISP, all of the sudden you will loose connectivity to the internet unless you pay A LOT of money to have a second line put in. Even then the chance that both of those lines run through some common area is pretty high.
Things are easy to engineer with fully redundancy, what isn't easy is to do it cheaply enough that people will still be willing to pay for it.
