Are you having a issue with viewing a web site while others are able to view the web site from another computer. This might be a simple case of changing your computers DNS setting.
DNS
DNS servers are operated by your Internet service provider (ISP) and are included in your computer's network configuration. If you can access a website from a cellphone on 3G, neighbours computer or office, your ISP could be the source of the problem. If a website change their ip address your ISP should also update their DNS. This update can be slow on some providers. Also if the DNS server of your ISP is slow, the time it takes to resolve the web address adds up to the overall loading time of the website.

To flush your cache from your browser
The DNS (Domain Name System) is the service that translates web domain names into IP addresses so that you can connect to websites. If your local DNS files have been corrupted, you may not be able to load certain websites. Flushing your DNS will clear out your local DNS information and load a fresh copy.
- Windows - Press ⊞ Win+R and type cmd to open the Command Prompt. Type ipconfig /flushdns and press ↵ Enter. You will receive a message that the DNS cache has been flushed, and you can close the Command Prompt.
- Mac - Open the Terminal from the Utilities folder. Type dscacheutil -flushcache and press ⏎ Return. Then type sudo killall -HUP mDNSResponder and press ⏎ Return to restart the DNS service. You'll be prompted for your admin password.
