Russia bans Google Cloud, Amazon, Azure, Digital Ocean, Online.net, Hetzner, OVH, others
Over the past few days almost 20 million IP addresses were blocked in the country by Russia's communications watchdog Roskomnadzor, in an attempt to deny users access to Telegram messenger, which has refused to cooperate with the country's FSB (ex. KGB) security agency to provide secret keys to user's encrypted messages.

Apparently Telegram is deploying connection proxies across various cloud providers to allow people to continue using the program evading the blocks of Telegram's own AS and IPs, and Roskomnadzor in response cuts all access to those providers entirely.
If you as a hosting company get any request to block or remove services or IPs used by Telegram LLC, please do not cooperate with those requests, do not support stifling of users' privacy and freedoms which has been condemned by the UN. Even if you get your networks blocked in Russia, this has went to such scale that this can't continue for long, they will have to step back eventually, just do not support them and don't let them "win" easily.
