Mirror Mirror…on the Web!

According to Wiki: “On the Internet, a mirror site is an exact copy of another Internet site. Mirror sites are most commonly used to provide multiple sources of the same information, and are of particular value as a way of providing reliable access to large downloads.

Reasons:

Mirroring of sites occurs for a variety of reasons.
  • To preserve a website or page, especially when it is closed or is about to be closed.
  • To allow faster downloads for users at a specific geographical location. For example, a U.S. server could be mirrored in Japan, allowing Japanese Internet users to download content faster from the local Japanese server than from the original American one. This may be viewed as caching on a worldwide scale.
  • To counteract censorship and promote freedom of information. For example, an activist might post pictures on a website of a company conducting illegal activities or make available information on secret government activity and be litigated for such. Other internet users will make the content in question available on other servers when the legal action results in the cancellation of ISP or DNS services for the original activist.
  • To provide access to otherwise unavailable information. For example, when the popular Google search engine was banned in 2002 by the People’s Republic of China, the mirror elgooG was used as a way of effectively circumventing the ban.
  • To preserve historic content. Financial constraints and/or bandwidth prevent the maintainers of a server from keeping older and unsupported content available to users who still may desire them – a mirror may be made to prevent this content from disappearing.
  • To balance load. If one server is extremely popular a mirror may help relieve this load: for example if a Linux distribution is released as an ISO image onto the distribution developer’s own server, this server may become overloaded with demand. Alternative download points allow the total number of download requests to be spread among several servers, maintaining the availability of the distribution. Metalink is frequently used for automatic load balancing by listing all mirrors.
  • As a temporary measure to counterbalance a sudden, temporary increase in traffic. For example, Slashdotted websites will often be mirrored by a few slashdot posters until the article is pushed off the front page.
  • To increase a site’s ranking in a search engine by placing hyperlinks from each mirror to every other mirror (a technique known as link farming). This is viewed as unethical by most search engine administrators and websurfers.
  • Rarely, as a form of plagiarism; this is, however, usually pointless, as a website popular enough to be worth plagiarizing will quickly discover the copy as soon as one of their many readers stumbles onto the plagiarized site.
  • As a form of raising advertising revenue. Wikipedia is probably the best example of material released under the GNU Free Documentation License which is then duplicated by other companies which, unlike Wikipedia, then attempt to generate money from advertising, etc. See Wikipedia:Mirrors and forks.
  • To serve as a method of circumventing firewalls.

I would have put it in my own words; but Wiki gives a simple and clear information!

For Top Marketing Review Blog though; the Mirror Site is a temporary solution to balance Load. No Link Farming, No Rank Improvement and no attempt to raise Ads Revenue…etc.
