huge packet loss on nlede01 
  Shadow Hawkins on Wednesday, 26 July 2006 07:55:51
Good morning,
i am experiencing quite huge packet loss for the last couple of hours via nlede01 from my machine to various other machines on the IPv6 network.
Find below a traffic statistic from my machine to one and the same machine once via IPv6 and once via IPv4. None changes on my side which could explain this traffic loss.

I can confirm this issue. Please take a look at these performance graphs for 2001:7b8:2ff:113::1, my IPv6 gateway at nlede01.

Something is definitively broken.

huge packet loss on nlede01 
All say "Thank you United Colo and their ddos kids"
They have a customer who is sending about 180mbit/s of spoofed 6to4 traffic to the 6to4 relays and this, after other 6to4 operators turned their relays off ended up on nlede01 which also runs a 6to4 relay.
