Just today I noticed that my links to documents on hraunfoss give me a 404 error (page not found). I have feared the disappearance of hraunfoss since 2010. We went through a "transitions.fcc.gov" phase, and a flirtation with "www.fcc.gov/document/...." Could the reign of hraunfoss finally be over?
One encouraging sign: the FCC links are all broken, too. Try going to the list of 2011 WCB appeal decisions; it looks like 800some broken links. It wouldn't be the fist time that hraunfoss had trouble getting started on a Monday.
In the short term, you can get at the documents by editing the URL: take out "http://hraunfoss.fcc.gov" and put in "https://apps.fcc.gov" at the start of the Web address. Note that you have to put an "s" after "http." Perhaps that will be hraunfoss' demise: everybody's moving to https, and as long as you're going to have to change every URL....
