Hi folks,
Here are the networks that have ignored me so far. If you are a contact
for them, if you know the contact for them, peer with them, talk to them
on the golf course, whatever - get them out of bed, wake them up, and get
them to fix their routers *NOW*. If you are their uplink, block their
traffic or otherwise disconnect them until they fix their routers.-dalvenjah

Whups. That's a corporate block for desktops that will be going
away within the week as HQ moves to san jose. I'll bug the folks
responsible for it. 
My apologies for the trouble it may have caused!
