Це не чутливий контент – це реальне життя України та українців. Херсон. Зранку, у суботу, у переддень Різдва, у центральній частині міста. Це терор, це вбивста заради залякування та задоволення. Світ має бачити, проти якого абсолютного зла ми воюємо. #russiaisateroriststate

Пройшли сотні років, а кацапи діють тими ж методами, шо і дика орда під час навали на Київську Русь, налетіли, сплюндрували, вбили, пограбували і пішли. Час спливає, а дикуни залишаються дикунами.

Remember when last year on 5th Feb 2021 there was an attempt to block twitter in Myanmar, causing a route hijack? manrs.org/2021/02/did-someon… The only difference between that hijack and today's hijack is "Valid" ROA as explained by @DougMadory teapawt.net/DougMadory/status/1508… @RoutingMANRS
Did someone try to hijack Twitter? Yes! - MANRS

Did someone try to hijack Twitter? Yes! - MANRS

On 1 February, Myanmar’s army took power in a coup against the elected government and detained the civilian leadership. Restrictions to the Internet were reported as people woke up to the news....

From 12:05-12:50 UTC, RU telecom RTComm (AS8342) hijacked a prefix (104.244.42.0/24) belonging to Twitter. The hijack didn't propagate far due to a RPKI ROA which asserted AS13414 was the rightful origin. This is the same prefix hijacked during the coup in Myanmar last year.

We asked @ukrnames if they intentionally stopped announcing the netblocks in question – "Yes, we confirm it. We stopped announcing the subnets as result for Russian attack to Ukraine."

Hm, Ukrainian domain registrar (@ukrnames) withdrew several BGP routes today, then some of the same routes started getting announced out of Russia. What's going on here? (Good catch @heymingwei!)

With the world’s eyes on Kyiv, I’m rereading former Chechen foreign minister Ilyas Akhmadov’s account of the 1994 battle of Grozny, when Russian forces rolled in to the Chechen capital on New Year’s Eve hoping to quickly knock out an underdog enemy. smallwarsjournal.com/documen…
