Why were the NPS web sites shut down?

Recent news in Archaeology magazine about the NPS web site class action shutdown. The NPS web sites have been back up and operating, but when the problem will be resolved, is unknown to date.   Since the United States National Park Service manages all the national parks in the US, they also host the web sites giving the public information on those sites/parks and in many of those parks are numerous archaeological sites.  Several years ago, the NPS began to create web pages for these sites,  with information on everything from the archaeological history of the sites, to the interpretations of their previous inhabitants, to the hours and days the sites are open to visitors. These sites had been shut down due to a bureaucratic nightmare of redtape involving government bureaucracy, computer security issues, and the mismanagement of funds at the United States Department of Interior.
Since modern America is composed of a new world created by the descendants of European colonists who took, bought, bartered, tricked, and/or stolen the lands from its original Native American inhabitants; America has recently been trying to repair, especially culturally and historically, the damage its founding fathers and mothers has caused.  In 1934, the US Government began holding lands “in trust,” supposedly keeping that money for over 300,000 individual Native Americans. Due to the fact that  the accounts were never well-maintained and today are so confused that no one has even been able to balance the account for decades. Yet the U.S. government continues to spend the allocated money. In 1996, this was discovered, and a class action suit (called the Cobell case for the name of its litigators) was filed against then-Secretary of the Interior Bruce Babbitt, claiming that the US Government had grossly mismanaged and continues to mismanage funds which were to be held in trust for the Native American community. Babbitt admitted that the accounts were a mess but could not be straightened out at this time. The class action suit and court cases continued, now against present Secretary of the Interior Gale Norton. In December 2001 -   the list of owners of the trust was discovered in a non-secured electronic file, and was accessible to anybody in the Department of Interior, as well as computer hackers who could potentially go into the file and change it. The court ordered the DOI, and all of its branches, including the Department of Natural Resources, to shut down all of its Internet connections. While The NPS websites are active again, the class action suit is still being fought.
