What I'm seeing from on my personal network connections is a lot of traffic to udp port 1434 start at 05:30:08 UTC. The sources appear very widespread, but I'm also seeing different affects on networks. Some backbones are being hit extremely hard, while others are just moderately impacted. I haven't figured out if it is a customer base difference, or if the worm is targetting. I haven't been willing to sacrafice one of my personal computers to the cause, so I don't know what's in the payload. According to Matrix Systems, there was about a 10% drop over the next 30 minutes. Keynote's data shows several backbones impacted. BGP and DNS appear to be holding up more or less, but g.root-servers.net has left the building (may be self-inflected withdrawal). Cable & Wireless's sla.cw.net show no impact on their network. UUNET's network status web site says Normal. Earthlink's network status web site shows various maintenance activity. SBC's network status web site says dial and dsl is Impaired. I can't reach www.sprint.net. AT&T's network status is unavailable while service enhancement is being performed.
