Unfortunately it is impossible to access www.setbb.com
even by IP-address (diagnostic "Connection timeout"). "ping www.setbb.com
" or "ping 18.104.22.168" don't work in the same way. I've tried to access site by 5 different Internet providers in 2 cities in Russia and failed to do it in all cases. I consulted with Internet expert. He is sure the cause is incorrect network setting on this site that limits access by Internet to this site for some regions (for example, for Russia).
So, good-bye, www.setbb.com
I am planning to send my problem description to ruud
(I think he is the setbb.com/sudoku forum administrator)
