Access denied, by most exits, to a very specific IP range
The IP ranges in and around 220.127.116.11 (although is seems to be generalize around, approximately, 18.104.22.168/28) are blocked from the majority of TOR nodes. I have tried a wide variety of "new TOR circuits", and nearly all of them have such a block in place. This includes http (port 80), https (port 443), DNS (port 53), and other likely ports, (i.e. cPanel).
I have equally tested through a quantity of free proxies (not TOR related), and blocks do not exist to this IP range through any of them.
All indications are that this block by TOR began on, or shortly after 24 April 2015.
