Russia’s telecommunications Roskomnadzor, blocked over 1.8 million IP addresses belonging to Amazon and Google’s cloud infrastructure.
The following IP addresses blocks have been restricted in Russia at the ISP level. The IP ranges account for 1,835,008 IPs.
18.104.22.168/15 22.214.171.124/15 126.96.36.199/15 188.8.131.52/15 184.108.40.206/14 220.127.116.11/12
The move to ban these IP blocks is a response to Telegram moving some of its infrastructure to Amazon Web Services and Google Cloud servers over the weekend.
Roskomnadzor banned the Telegram instant messaging client inside Russia’s border on Friday, April 13, after Telegram refused to hand over customers’ encryption keys to the FSB, Russia’s main intelligence service.
