title: unable to access web site
body: <p>My website (<a href="http://harlequinf40.info" rel="nofollow">harlequinf40.info</a>) (WordPress) is only intermittently accessible.
  On my home WiFi network, it is accessible from Chrome on my W7 PC but not in Chrome on my W8 laptop or my Android phone. They both return a blank screen.</p>
  
  <p>On the phone, using a proxy server, I get "the requested URL was not recognised as a valid URL", whereas on my W7 PC, using the same proxy server (<a href="http://free-proxyserver.com" rel="nofollow">free-proxyserver.com</a>), I get to the site OK.
  Some of my users are also unable to access the site, others are getting on fine!</p>
  
  <p>I'm not getting a 404 error, or any response...just a blank screen.</p>
  
  <p>I have started to talk to my ISP, but it's a big telco and they're not very responsive(!)
  Any suggestions?</p>
