So you must try all of the tricks given before reaching the conclusion that you cannot access a website. Some of the tips given in this article can also be used to prevent your surfing and IP Address from being logged. So, let us begin:-
CacheGoogle and other search engines maintain a cache of web pages that are spidered by their robots and are present in their index. This cache(snapshot) of the web page is saved by Google as a back up in case the original page is unavailable. This can be accessed by clicking on the cached link besides the search results that appear for search queries. The cached version of the page might not be the latest version of the website but nonetheless, you can still use it to visit the web site of your choice. Another way to view the cached version of a web page is by using the 'cache:example.com' search query.
Internet Archive( Wayback Machine)Internet Archive is a non-profit organization which stores websites in an archive form using which you can see how the website looked at a specific time. This is similar to a saved copy of the website on your local hard drive. Just visit Wayback Machine and enter the address of the web site you wish to visit to see if a cached copy of it is available. This archive can also be used to access websites that are suspended or down.
Translation ServicesTranslation Services like Google Translate and Yahoo! Babel Fish can also be used to unblock websites. Enter the URL of the website in the translation field. Select a different language than the one on the website in the "Translate From" field, and the language you read in the "Translate To" field. e.g. If the web page is in English, select an other language like Spanish in the 'Translate From' field and English in 'Translate To' field. This method can be effectively used to access restricted websites.
Changing HTTP into HTTPSThis is the fastest way to gain access to restricted websites. To use this method, just change the 'http:' in your URL to 'https:'. This can confuse the software which is blocking the site you wish to visit. Although this might not work every time, it still is a handy trick to tackle not so complex website blocks.
IP Address of the Website as AddressThis is probably the most effective way to access blocked websites. To use this method, first you need to find the IP Address of the website you wish to visit. You can use the command prompt and type 'ping mydomain.com' to get the IP Address of the restricted website. Now that you have the IP address of your website, just enter it in the address bar of your web browser and press Enter. It is highly probable that the website you wanted to visit will be unblocked.
