its dynamic front ends, MySQL at the database back end, Sphinx on the two search systems, memcached for caching SQL queries and PHP-sessions and Varnish in front of Lighttpd for caching static content. , The Pirate Bay consisted of 31 dedicated servers including nine dynamic web fronts, a database, two search engines, and eight BitTorrent trackers. On 7 December 2007, The Pirate Bay finished the move from Hypercube to Opentracker as its BitTorrent tracking software, also enabling the use of the UDP tracker protocol for which Hypercube lacked support. This allowed UDP multicast to be used to synchronise the multiple servers with each other much faster than before. Opentracker is free software. In June 2008, The Pirate Bay announced that their servers would support SSL encryption in response to Sweden's new wiretapping law. On 19 January 2009, The Pirate Bay launched IPv6 support for their tracker system, using an IPv6-only version of Opentracker. On 17 November 2009, The Pirate Bay shut off its tracker service permanently, stating that centralised trackers are no longer needed since distributed hash tables (DHT), peer exchange (PEX), and magnet links allow peers to find each other and content in a decentralised way. On 20 February 2012, The Pirate Bay announced in a Facebook post that after 29 February the site would no longer offer torrent files, and would instead offer only magnet links. The site commented: "Not having torrents will be a bit cheaper for us but it will also make it harder for our common enemies to stop us." The site added that torrents being shared by fewer than ten people will retain their torrent files, to ensure compatibility with older software that may not support magnet links. Funding Early financing In April 2007, a rumour was confirmed on the Swedish talk show Bert that The Pirate Bay had received financial support from right-wing entrepreneur Carl Lundström. This caused some consternation since Lundström, an heir to the Wasabröd fortune, is known for financing several far-right political parties and movements like Sverigedemokraterna and Bevara Sverige Svenskt (Keep Sweden Swedish). During the talk show, Piratbyrån spokesman Tobias Andersson acknowledged that "without Lundström's support, Pirate Bay would not have been able to start" and stated that most of the money went towards acquiring servers and bandwidth. Donations From 2004 until 2006, The Pirate Bay had a "Donate" link to a donations page which listed several payment methods,
