Hi tor-relays@,
While I don't live in Russia, nor are my parents from Russia (they're from India), today, I noticed these articles that some people noticed Tor is blocked in Russia (sorry for being late):
https://ntc.party/t/ooni-reports-of-tor-blocking-in-certain-isps-since-2021-... https://forum.torproject.net/t/tor-blocked-in-russia-how-to-circumvent-censo...
Yet, when I look at Tor Relay Status, I noticed many relays hosted on Russian residential ISPs are still online, and only a few aren't:
Moscow City Telephone: *https://metrics.torproject.org/rs.html#search/as:AS25513
Rostelecom:
- https://metrics.torproject.org/rs.html#search/as:AS12389
- https://metrics.torproject.org/rs.html#search/as:AS42610
- https://metrics.torproject.org/rs.html#search/as:AS34168
Vimpelcom:
- https://metrics.torproject.org/rs.html#search/as:AS8371
- https://metrics.torproject.org/rs.html#search/as:AS8402
MTS:
As it was mentioned on ntc.party thread, some ISPs are anomalous:
"Note that AS 12389 of Rostelecom is in the above blocked list, but that AS and other ASes of Rostelecom are also in the below unblocked list. Also note that AS 16345 is in both lists—there was one normal measurement for this AS, but about 30 blocked ones."
I didn't notice a big reduction in "relay" users on Metrics: https://metrics.torproject.org/userstats-relay-country.html?start=2021-09-06...
But did see an increase in "bridge" users: https://metrics.torproject.org/userstats-bridge-country.html?start=2021-09-0...
FWIW, the last Tor Metrics stats are from December 03, so we will see a change on the graph in the next days. (This event started on December 1).
Another interesting graph: https://metrics.torproject.org/bridgedb-distributor.html
This spike on Moat could mean users are trying to get a working bridge, but moat bridges aren't functional, so they try again and again... As mentioned by ValdikSS.
And most Ooni results still show Tor can connect fine: https://explorer.ooni.org/search?until=2021-12-06&since=2021-11-29&p...
Yup, it's a partial block.
I feel it could be possible it's one of the two:
- Most likely, the censorship rollout is in stages. Some users are blocked
but other's aren't, where it wasn't rolled out is still unblocked.
Probably. We're getting a lot of messages in Russian on our support channels. So, yes, although it's not a country wide Tor block, some users in Russia are experiencing censorship.
Remember that Russia is in the #2 in the Tor users rank: https://metrics.torproject.org/userstats-relay-table.html
- Less likely, but Russia found people could use pluggable transports, like
HTTPS obfs4 bridges and maybe they found blocking Tor itself is ineffective, or trying to block "meek" users ended up blocking Microsoft and ASP.NET/Azure-based webapps.
I don't think so.

ps: IMO, this thread should move to anti-censorship team mailing list https://lists.torproject.org/cgi-bin/mailman/listinfo/anti-censorship-team
Disclaimer: I work at Microsoft, but not on Azure as of now. I did however interview for a position in the Azure umbrella (not on the CDN however).
