We've had complaints from people at the other side of Broadwing connections -- anyone here from Broadwing? Looks like you may even be stripping 72.0.0.0/8 from BGP announcements.

Wash, rinse, repeat for the other 70,000 routers you manage for customers... This is definitely NOT a half-rack in a colo fix. Just contacting the customers is a feat.

In the same hand, do you know how hard it was to get in touch with someone at SBC/SBC-IS/PBI/PacBell that knew what the heck I was talking about -- much less someone that might be able to do something about it? Every group wanted to point their finger at some other group in the company...

Sure, start with the customer and convince them that there is a problem. SBC has, like sprint/att/mci/qwest/abovenet/blah-provider-of-managed-services 12 groups that do 'similar' things for 'managed customers'. Fighting their phone tree as a non-customer is a fruitless effort. Fighting the phone-tree for gov't agency #13 to let them know that some of their 'customers' aren't able to reach them might prove simpler. -Chris
