Russian crackdown on rebellion and pro-Ukraine hackers.

Russian authorities blocked access to major news sources and information from the Wagner mercenary group as it pushed toward Moscow on Saturday, adding to the confusion as rumors and misinformation about events flourished. Google News was blocked beginning Friday night by Rostelecom, Russia’s largest digital provider, along with at least four other major internet service providers, according to the nonprofit group NetBlocks, which monitors internet censorship. Telegram, a messaging, news and social networking program that is widely popular in Russia, had significant outages in cities including Moscow and St. Petersburg, as well as points on the route to the capital from the southern city of Rostov-on-Don, which Wagner troops controlled.
