I’m posting to the twitter news from my site using Perl library “Net::Twitter::Lite::WithAPIv1_1”.
From yesterday it stop working throwing and errors “500: Can’t connect to api.twitter.com:443” 
It looks like IP of my server is banned, because when I’m doing “wget api.twitter.com:443” I got:
–2014-07-31 18:49:06-- http://api.twitter.com:443/
