Anton's post that GX is still providing them transit is a bit curious, since
I was under the impression GX had severed all ties with Atrivo.  But the
table does not lie, a path of "174 3549 27595" is clearly transit.  GX, care
to comment?

After poking for a bit, it's unclear what, if anything, GX is or isn't
doing here.

I tossed a static /24 towards the upstream sending the AS path with GX
in it, and traced towards a host in the that /24 - the traceroute
output disagrees with the as path, oddly enough.

bgp routes, again:

r> 58.65.238.0/24   71.13.116.101   100   0   20115 19151 27595 i
r                          204.11.128.105   100   0   33125 174 3549 27595 i

actual path is cogent, (3), wv, intercage, not cogent, gx, intercage:

question I have for the list is...who's faking the funk?

second that...

from ripe bgplay view, gx is never seen as an adjacency to 27595, just
wv and bandcon, with liteup being brought up later on in the 2 day
interval
