Re: Anyone else having trouble reaching thepiratebay.se? AS39138

[Courtney Smith <courtneysmith () comcast net>]

I just posted TATA as a single example.  This route is missing from multiple networks.  I could not find the specific 
/24 on, Sprint(1239) AT&T(7018) and Centurylink either.

rviews () route-server ip att net> show route 194.71.107.0/24 

rviews () route-server ip att net> 

from https://www.sprint.net/lg/lg_start.php

Query Results:

Basic troubleshooting of your two example ASN's.  Notice the community 174:991 on the Cogent path?  Go look that up in 
Cogent's community guide.  Level3's looking glass actually does the translation of communities for you.  I'm not going 
to try to map out all the possible paths this prefix could be reach.  At the moment, the /24 is not reachable from 
several networks.  Either an outage or a change at AS51040 or  their upstreams has caused the traffic engineering of 
one of the networks upstream of 51040 to break connectivity for a group of networks.
