Russian MoD website blocked for non-Russian IPs

It appears [1] that Russia's Ministry of Defense website is getting blocked for all IPs outside of Russia.

This seems deliberate as the request's answer is a HTTP 418 :

  $ curl -v "https://eng.mil.ru/"
  *   Trying 82.202.189.138:443...
  * Connected to eng.mil.ru (82.202.189.138) port 443 (#0)
