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)). core1#traceroute 72.246.89.243 source 66.249.106.113 Type escape sequence to abort.
