Illuminet ss7 cable cut (was Re: New York City: ATT Local Service (TCG))
by Sean Donelan 29 Jun '00

29 Jun '00

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.

I guess Illuminet As I said, its a quirk in the FCC reporting regulations. Illuminet has relatively few direct customers (just a few IXCs and CLECs), so it never triggers the 30,000 customer regulation. On the other hand, carriers are not required to report outages in leased facilities from other carriers. Only the immediate supplier is required to report the outage. Put the two together, and you can have a wide-spread outage affecting lots of end subscribers, but is not reportable.

New York City: ATT Local Service (TCG)
by Sean Donelan 29 Jun '00

People are reporting that AT&T local services (TCG)in New York city has died in a very nasty way. Not only did ALS lose its circuits, but all the ALS customer service numbers from the area are out of order too, hence folks have sent me mail asking if I know what's up. I don't know, anyone with some info?

It may or may not be related, but a local TV station (channel 4) reported a major Bell Atlantic fiber cut. They said that it affected Bell Atlantic long distance customers from "Virginia to Maine", and that customers of AT&T, MCI, and Sprint might also be affected. --Steve Bellovin

The goal of a scientist is to find an interesting problem, and live off it for a while. The goal of an engineer is to evade interesting problems :)" -- Vadim Antonov <avg(a)kotovnik.com> on NANOG
