Spamhaus, URIBL, SURBL under DDOS attack

This has been ongoing for a couple of days now. Spamhaus and two other major blocking list providers have been under a distributed denial-of-service (DDOS) attack. Steve Linford of Spamhaus believes that the source of the attack is the same people who executed the attack against Blue Security last year which effectively destroyed their Blue Frog anti-spam project.

Spamhaus has implemented anti-DDOS countermeasures and is weathering the storm. Uribl has closed up shop, redirecting their IP address to 127.0.0.1 until things blow over. (One wag has suggested that they redirect to 255.255.255.255 in order to get the attention of the ISPs hosting the zombies. Bit of network geek humor there.)
