out of 47000 routes from Agis, 7327 of them have 7007 in them.

I spoke to them and they said that thier router broke..


They won't give us an answer, but when I said I was from Net Access, he
said "nac.net?" like he knew me, and they were vague. They also claimed
that they had 'turned thier router off', but the routes were still in for
almost 25 minutes later. Not only that, it seemed mailcious to me,
because the only announced the /24 of our name servers (207.99.0.0/24)
and not our whole /17. 

Are your nameservers in the first class C of your CIDR block by any
chance???  They have been taking CIDR blocks and squirting out 
Class C equivilents.

Sadly, many poeple (including me) think, oooh, nice big CDIR block lets
put all my important boxes in it's first Class C... Seems to be a 
very bad descision ;-(
