Going through GLBX I get right to 205.232.34.1....

The problem seems closer to the zloc rather than cogent.

Both routes go through 66.152.113.44 ,,,, Maybe local firewall/acl
rule @FINGER LAKES TECHNOLOGIES GROUP, INC.?
Sorry for the caps but cut/pasted from rwhois :-)
Correct me if you see different results :-)
