Hello,

We have been assigned 66.249.96.0/20 in April of 2008. Little did we  
know that this network was used by a spammer in 2004 (Lightwave  
Transit) and with this is deeply
embedded in a lot of ACL's that seem to be unmaintained.

If a GLBX engineer could take a look, it seems traffic originating  
from 66.249.96.0/20 can't reach some website when passing thru GBLX.  
Other prefixes we announce from our AS (22442) such as 66.60.224.0/20  
don't have this problem.

Customer with source of 66.249.106.112/27 can't get to the website of www.ups.com 
  (72.246.89.243 (akamai)).

I tried an email to their puck noc email address, but without being a  
customer I can't open a ticket.

Thanks,
