Yep, can’t connect to my site from all of my RegRu servers to my RegRu servers through the cloudflare. You can check site availability from different places here: https://ping-admin.ru/free_test/

104.27.181.0/24 network isn’t reachable from TELE2 mobile network in Russia too. While MEGAFON and MTS works fine. Also Fiord peering with CF doesn’t work when I try to access this network. The interesting fact is that some other web-sites that are on the different subnets have no such problems (e.g. 104.26.6.0/24). This behaviour started at 18:52 UTC.
