Tunnels inoperative in Russia

Recently Tunnels became entirely inoprtative in Russia. I have a server there that I use Tunnels to access. I found a very small group of other people with the same issue on Russian censorship circumvention forums; presumably Tunnels are not that popular. This started happening at the beginning of the month, and slowly got worse and worse until it could simply not connect anymore. Logs below.
