on october 20, 2006, dmoz's main server suffered a catastrophic failure that prevented editors from working on the directory until december 18, 2006. during that period, an older build of the directory was visible to the public. on january 13, 2007, the site suggestion and update listings forms were again made available. on january 26, 2007, weekly publication of rdf dumps resumed. to avoid future outages, the system resided on a redundant configuration of two intel-based servers from then on.
