Popular file-sharing site KickassTorrents (KAT) has been down due to intellectual property and piracy parameters, but there are mirror and alternative sites that users can feast on. 

KickassTorrents has suggested five alternative mirror sites for users who cannot access their main website. The sites are http://kat.cr, http://kickass.to, http://kickasstorretns.to, http://kickass.cr, and http://kat.am. In case the mirror sites don't work, there are other sites recommended to be used as well.

As of this writing, Kickass primary domain is working fine and the notices that appear are "All systems are up and running" and "There are currently no known issues."

The condition may change at any time though with the arrest of its alleged owner, Artem Vaulin, in Poland. The case is being handled by high-profile technology lawyer, Ira Rothken, who is best known for representing Kim Dotcom.

Techworm has listed five popular alternative sites to KickassTorrents as well, namely Torrentz, The Pirate Bay, ExtraTorrent, YTS/YIFY, and RarBG.

Torrentz was the third most popular torrent site when the year started and, after KAT was shut down for some time, it has become the top torrent website at the moment. It works by directing users to search results from other similar websites.

The Pirate Bay started in 2003 and was considered one of the first websites of its kind. The site has also been shut down from time to time and has switched to several domains to stay afloat. Its co-founders are currently facing legal issues as well.

Extra Torrent is consistenly on the top list of torrent sites. It is popular for its easy search design that presents proper category listing of its content.

YTS/YIFY is currently under the name YTS.AG after the original website has shut down seemingly for good. Its design has attracted many users because of the way it presents its content.

RarBG quickly rose to popularity after it was launched in 2008. The website is blocked from some countries such as the United Kingdom, Saudi Arabia, Denmark, and Portugal, but it remains to be popularly used in other countries such as the United States.
