A message was posted on the homepage stating that "We might have to shut down everything to fix and prevent further damage," and that it could be "days maybe, until we can change the power circuit."[28] During the downtime that followed, several new messages appeared, mostly providing updates on the repair status and promising that the site would return soon. On November 4, 2009, the tracker, which communicates with a BitTorrent client, began responding to some torrents, and returned to full operation on November 17. The main site, however, did not become operational until December 13, 2009.[citation needed]
