Anyone else having trouble reaching thepiratebay.se? AS39138

Thu Nov 27 02:18:01 UTC 2014

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 at route-server.ip.att.net> show route 194.71.107.0/24

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.

But Verizon peers with the same ASNs I do 3356 and 174 which both have routes to thepiratebay’s prefixes, and I can almost guarantee that Comcast has those routes within your network.  What’s up really?  Just because TATA is  blocking routes shouldn’t effect the whole internet, or this whole thing would have been screwed a long time ago.
