Comcast security NOC/contact

Can someone from Comcast please contact me over what appears to be an ill-conceived nullroute or block regarding one of our content IP's. This issue is limited only to Comcast and only to a single IP. Please contact me to get this resolved. I'm guessing that someone wanted us offline but couldn't do it directly. So they attacked you using our spoofed IP, and your automated systems put a block in place. It would also be nice to have an actual, real NOC number listed in your whois. -richard
