Dear Robin,

Many thanks for the detailed instruction.

It seems loading bootstrap.min.js takes forever. When I copy this request 
as curl and try it at the command line, it also takes forever.

For www.gentoo.org it is about 100 ms; for wiki.gentoo.org 300-400 ms, not 
too bad.

This is highly probable. I read somewhere that Russia blocks some CDNs 
because they transfer urls encripted, thus hindering the Big Brother's 
ability to spy on the users.

The command

curl 'https://assets.gentoo.org/tyrian/v1/bootstrap.min.js'

with the headers provided by chrome still has not terminated (about 10 
mins). I haven't tried to change the headers yet.

Once more, thank you,
Andrey
