If the site is UP but you cant access the page, try one of the solutions below:
Browser Related Problems
- Force a full refresh of the website. This can be achieved by pressing CTRL + F5 keys at the same time on your favourite browser (Firefox, Chrome, Explorer, etc.);
- Clear the temporary cache and cookies on your browser to make sure that you have the most recent version of the web page;
Fix DNS Problems
- A Domain Name System (DNS) allows a site IP address (192.168.x.x) to be identified with words (*.com) in order to be remembered more easily, like a phonebook for websites. This service is usually provided by your ISP;
- Clear your local DNS cache to make sure that you grab the most recent cache that your ISP has. For Windows: (Start > Command Prompt > type "ipconfig /flushdns" and hit enter);
- If you can access a website at office or from a 3G network yet it's not working on your computer, it is a good idea to use an alternative DNS service other than your ISPs. OpenDNS or Google Public DNS are both excellent and free public DNS services;
