I have a DSL connection in Ubuntu 11.04 and am having problems loading content from certain websites(such as heroku.com, ubuntuforums.org) mostly providing CDN services, though google and gmail run perfectly.
I have tried every suggestion asked at problem loading internet pages as I have the same problem. Also tried to remove the DNS Cache and Browser Cache.
I have tried using Google DNS Server: 188.8.131.52 and 184.108.40.206, but nothing seems to work. Though when I browse the websites in Windows XP then it does not pose any problem.
This problem has come up only few days ago and has affected every browser(Chrome, Firefox and Opera) in Ubuntu 11.04.
Thanks in advance.
