Re: [outages] Verizon Business OC-48 in Philly, S. New Jersey down
I've seen plenty of SONET "rings" where both sides are in the same cable. Not too much protection when doing things that way... I think the southern cross cable system had some customers that discovered several years back that running production traffic on both sides of your ring can seem like a great way to double capacity until a major storm goes through and blows away one of the cables and you don't have any capacity left for protection on the remaining side of the ring.

This is very similar to an XO OC-48 fiber cut that happened back in July. Same areas were effected, South Jersey and Phila. XO was down for 27 hours. The OC-48 may well have been Verizon - wonder whats going in Jersey with these OC-48 cuts?

Confirmed fiber cut of a OC-48, still dead, Philadelphia metro area, and the current status report is:
"Michael(20:43:14): Your circuit is impacted by a cable cut. Technicians are still at work. In the North Pit, they have excavating the damage and they are prepping the cable for splicing. In the South Pit, they are still excavating the damage."
No hint as to how much more was cut at the same time or ETR. But I was thanked for choosing Verizon. :-)

Or so goes the claim for why a bunch of our DS1s in that area all went away ~16:21 UTC. No ETR supplied to us; actually getting any hard data out of them right now is proving difficult.

A problem probably as old as chariots. Management does not understand the notion of "spares". They understand paying for stuff in revenue service, and does not understand paying for stuff not in revenue service. -- Somebody should have said: A democracy is two wolves and a lamb voting on what to have for dinner. Freedom under a constitutional republic is a well armed lamb contesting the vote.

Then management wasn't charging appropriately. It wouldn't be seen as a 'spare', then.
