#6869 — Vandalism in Arizona Shut Down Internet, Cellphone, Telephone Service Across State

Quoting from the URL above:

   Cellphone, Internet, and telephone services across half of Arizona went
   dark on Wednesday after vandals sliced a sensitive fiber optic cable,
   according to those familiar with the situation. The incident is raising
   concerns about the safety of U.S. infrastructure.

   The outage shut down critical services across large parts of the state,
   preventing individuals from using their phones, bank and ATM cards, and
   the Internet. Critical services, such as police and state government
   databases, as well as banks and hospitals, also were affected as a
   result of the vandalism.

   The services first went dead around noon MST on Wednesday, causing
   complete service interruptions across half the state, from Phoenix to
   such northern cities as Sedona, Prescott, and Cotton Wood, according to
   an official from CenturyLink, the Louisiana-based communications company
   that owns the severed line.

   "There was a vandalism that took place on a fiber optic cable that
   basically runs from Phoenix to Northern Arizona," said Alex Juarez, a
   spokesman for CenturyLink in Arizona.

   The line, which is composed of extremely thick cable, appeared to have
   been cut with a hacksaw, according to Juarez. Phoenix police are
   currently investigating the incident and say they have yet to determine
   a motivation for the crime.

   "We're not sure what the intent was, but they were able to cut the fiber
   optic cable, possibly using a hacksaw," Juarez explained. "It looks like
   a pretty straight cut."

With any luck, next time they'll go after a 500kV transmission cable.

And I was under the impression the internet had redundancy build in...

The design of the 'internet' has redundancy built in.

But in order for that 'design' to function as intended, the underlying
hardware which connects sites needs redundancy installed as well. 
I.e., there need to be at least two separate network paths over which
any given endpoint can be reached.

In this case, it appears that a whole swath of Arizona is supplied with
'network' connections via a single cable (i.e., a single point of
failure).


As an analogy to your home service.  Right now you likely have one ISP
supplying you with one network connection cable (does not matter if it
is cable, fios, dsl, etc).

If a block away from your house, someone cuts that one network cable
going to you, you are offline.

But, if you purchased service from two different ISP's (assuming you
even can), and they brought in two separate network wires, and someone
cut only one of the wires, you could still get to 'the internet' via
the second wire.


It seems that a large part of Arizona was wired much like most home
internet connections.  One single wire supplies all the bits to
everyone.
