title: This webpage is not available, The connection to xxx.domain.pl was interrupted, only first pageload
body: <p>I'm experiencing odd error while trying to load my web page in browser. When I haven't opened it for some period of time and then try to open it just by typing address in browser and clicking enter: 
  1) The page doesn't load - browser message that it is not available, connection to .... was interrupted 
    (in Opera there is also info about proxy, network... i can paste it later when error repeat again)
  2) after refreshing, loading page again it works ok (without any problem) 
     My web page address is crib.pl and subdomains niemiecki.crib.pl, hiszpanski.crib.pl 
     it is important to note that when i try first time load for example niemiecki.crib.pl then it doesn't open but next opening hiszpanski.crib.pl will open normaly also. </p>
  
  <p>Some additional info:
  - hosting is in bluehost (Utha, USA)
  - I'm trying to access this from (Poland, Europe)
  - website is on drupal 
  - it works for more than 4 years without problem on this server 
  - it works even week ago without a problem and it doesn't work since 31 december 2014 
  - bluehost support doesn't have any idea, they say it works perfectly 1-to-1 cases (no problem) 
    (If you can check it and type your country and whether yes/no you are expiriencing similar problem) 
  - I haven't modified anything on the web page (problem just happens without my interaction)
  - Google crawlers seems to have some problems with accessing robots.txt (sth like that) file
  - domain is hosted by company in Poland (crib.pl) and this domain is set using external DNS to bluehost.com servers</p>
  
  <p>Any help save my life, I'm experiencing about 50% drop in earnings since this problem!</p>
