You would think that ANY outage of this size would require an outage
report, no matter what the duration.
I imagine that if Illuminet customers actually provided any local service
(residential or business), this would cause a bit of a stink. If someone
couldn't make a life or death 911 call, even more so. ATTLS at least (the
one customer of Illuminet I'm aware of) sells very heavy to the dialup
market. The one customer I knew of that didn't fit the recip-comp
paradigm is NYU. I only know this because there used to be a piece of
paper hanging in the switch tech's office that reminded them they must
page some telecom manager there whenever there was a service disruption.
So even though this left thousands of dialup ports dead for at least 6
hours and left many dialup customers furious, I doubt that much will be
made of it outside nanog.
Nice loophole they have in reporting though.
Oh well. I guess Illuminet
stockholders can expect to see a loss... That is unless the CLECs and IXCs
who use them for interconnect were stupid enough not to require SLAs or
stupid enough not to enforce them. Then again, most dialup users, let
alone local/ld dialtone carriers have enforceable SLAs so, the CLECs and
IXCs probably have a battle ahead of them to get any compensation out of

The problem is with a Bell Atlantic cable cut affecting Illuminet. Illuminet
is a SS7 network provider which interconnects many different IXCs and CLECs
with the local ILEC. The cable is along Route 30 in Lancaster Pennsylvania.
This is not the first time a cable cut has taken out the SS7 signaling
in the Illuminet network. But due to the quirks in the FCC reporting
regulations, Illuminet hasn't reported any outage. Previously Illuminet
has a cable cuts in Illinois on February 26, 1998 and October 1997 which
disrupted many CLECs and IXCs. Instead of installing their own dedicated
circuits to every SS7 STP, they use Illuminet as a shared network. This
means a problem with a relatively unknown network has very widespread affect.
