addons addons.mozilla.org is being blocked by Russian authorities

"Roskomnadzor" (Federal Service for Supervision of Communications, Information Technology and Mass Media) is now blocking a wide range of IP addresses, including addresses that belong to mozilla: 34.192.0.0/10 34.192.0.0/10 54.64.0.0/13 So, the website is not always available to users in Russia.

UPD: +accounts.firefox.com by 35.160.0.0/13 & 54.144.0.0/12

I know how to solve this problem - VPN. But I wanted to notify mozilla team about what happened.

Thanks for the notification! We are aware of that but in the short-term there doesn't seem to be much wen can do. This appears to be related to the Telegram block.

Yes, it's consequences of attempts by the censor to block telegram. Even VPS which is used as a proxy server are blocked. It's a shame for the country...

Someone (preferably a russian individual) could file a report at https://rkn.gov.ru/treatments/ask-question/ . No guarantees about a swift reply though...

@roman90sv Can you check again? We got some reports that AMO isn't being blocked in Russia currently.

@jvillalobos It's no use, they keep on blocking/unblocking stuff randomly.

@roman90sv we asked people in Russia to try connecting to AMO and they didn't report any problems. I'm asking to try to figure out if this is a regional problem, a temporary one, or something else.

@jvillalobos The website is available now (for me). But it's not sure that the website will be available tomorrow. Some users complained about the problems with synchronization.

This is a regional problem (varies between ISPs)+temporary problem (blocking/unblocking IPs randomly everyday)+something else. :)

It seems that the set of IP addresses for addons.mozilla.org changes regularly, therefore the problem can appear and disappear again.

Yesterday addons.mozilla.org was resolving into 34.209.9.196, 35.166.74.225, 35.167.92.222; all those addresses were blocked in Russia (34.192.0.0/10 and 35.160.0.0/13 network ranges are blocked), therefore https://addons.mozilla.org/ was completely unreachable.

Today addons.mozilla.org resolves into 35.166.74.225, 35.167.92.222, 52.89.239.72. Two of these addresses (35.166.74.225 and 35.167.92.222) are still blocked in Russia, but the 52.89.239.72 address is reachable, therefore https://addons.mozilla.org/ is available, but with long delays caused by timeouts for unreachable addresses (my ISP just drops packets to blocked addresses).
