The official introduction page for the album reads:
:Nine Inch Nails presents Ghosts I - IV, a brand new 36 track instrumental collection available right now. Almost two hours of new music composed and recorded over an intense ten week period last fall, Ghosts I - IV sprawls Nine Inch Nails across a variety of new terrain.
On March 3, 2008, the day after the release, the following was put up in place of the ''Ghosts I-IV'' web site:
:Unfortunately, the Ghosts I-IV I–IV site is down for the next few hours for maintenance.
:We quietly released this album last night without any warning, and without any press. Because we know how devoted our fans are, we planned for an overwhelming response, and expected heavy traffic. To our surprise, the traffic was more than three times what we anticipated, and has only been getting heavier throughout the day. The response has been absolutely phenomenal, and we couldn't be happier, but our servers have taken a beating, causing numerous problems with the download site. Our developers, who have been working non-stop to combat the surge of traffic, feel that taking the site down for a few hours to fix some crucial issues is the best way to get things running smoothly again. We sincerely apologize for the inconvenience.
:While the site is down, you can still purchase the complete Ghosts I-IV I–IV here from Amazon's MP3 store for only $5. The MP3s are high quality and DRM-free. You can also order the deluxe and limited edition packages from Artist in Residence.
:If you're familiar with BitTorrent, you can download Ghosts I, the first of the four volumes, for free, from [http://thepiratebay.org/tor/4059158/Nine_Inch_Nails_-_Ghosts_I_(2008) our official upload at The Pirate Bay].
