Today, The Pirate Bay reached a new milestone, as they now have more than 3 million registered users. On top of that, they track close to 15 million unique peers. The largest BitTorrent tracker just keeps growing and growing, and there is no sign that this will be put to a halt anytime soon.

When this article is published, The Pirate Bay now tracks nearly 1,288,514 torrents and 14,786,539 unique peers. As a comparison, in December 2006 they tracked 576,080 torrents and 4,274,698 peers, so today’s figures represent quite an increase.

TiAMO, one of Pirate Bay’s co-founders and the one responsible for keeping the hardware up and running, is happy with the traffic increase, and writes:

“A big thanks to all our users helping to make the site what it is. We’ll keep growing for as long as you keep using the site, filing it with content, sharing.”

This traffic increase is apparently placing quite a lot of stress on their server park. In July, the site went offline for more than a day, as the server setup had trouble keeping up with the ever-growing demand. It is estimated that The Pirate Bay currently returns results to between 7 and 8 million searches per day, roughly 230 million a month.

The popularity of The Pirate Bay hasn’t gone unnoticed with artists either. Timbuktu, a well known Swedish rapper released his latest single exclusively on The Pirate Bay earlier today. Free of DRM, high quality and free to share and remix of course.
