Well, I guess we see this trend of making things less redundant and
less faithful to theory, more faithful to shaving off 1/4 of a cent
universally.
We see bomb threats pretty universally too, and not necessarily for
political reasons. Are you sure it wasn't just a kid whose computer
crashed again?
become
This is kinda off topic, but we've just had a
bomb threat!
No joke! Someone phoned in, asked for my boss, and said they
put a bomb in the building! Why would someone bomb an ISP?
Other than my boss is an Afican-American... (Native of Nigeria).

A sad commentary on a form of 'techno-terrorism' that is likely to more prevalent as dependency on the 'net'
increases.
The commercialization of the Internet has inadvertantly weakened one of
its major design points that was considered to be so critical when the
first ARPA designs were worked out. That being redundancy and lack of
centralization.
Before the major commercial 'backbones' were in place, (set the
'wayback'
machine; Sherman) most systems had multiple shared
dial-up connections
to
numerous other hosts with which they regularly shared
information
(email,
news, files, etc.)
If a network connection went down, (if you even had one) or a given
host
was offline, traffic was just routed thru another
system that indicated
connectivity to the system (or systems) that the traffic was destined
for.
(everyone remember the periodic routing 'maps'
that went around?)
So... unless you lost ALL of your phone lines for an extended period,
you
pretty much always had (some level of) connectivity.
Today, on the other hand (generalization warning!) how many major
systems
maintain dial-up inter-system capability even as a
backup?
The major infrastructures have tended to centralize around the
commercial
'backbones' and carriers which make them
succeptable to interruptions
of
service when a single connection fails! (Sure... your
web servers are
fed
by dual 'T3s', but both from a single carrier
thru a single POP?!?)
So much in money and resources is often committed to create/maintain a
major (high bandwidth) link onto the net, (useful) redundancy is
frequently sacrificed.
One attack on a major carrier POP (ok, definition time: POP = Point
Of Presence) could easily disrupt Internet traffic for a LOT of people
and
corporations.
Take out a couple of the major authoritative DNS servers, and watch the
world (generalization) start crashing down!
Or sadly, target one ISP that is suspected of being a major provider?
It happens... more often than you might ever imagine...
