The Inspector General for the Federal Communications Commission found that there was no denial-of-service attack during the public input before the FCC repealed net neutrality. The incident occurred in May of 2017 after an HBO host urged his audience to submit comments to the FCC supporting neutrality. The audience was blocked from filing comments as the system shut down. The FCC claimed denial-of-service attacks was the cause of the shut down. (Free Press, August 7, 2018, press release)
Dan Van Winkle, The Mary Sue, August 7, 2018, writes that the FCC hacking claim had little credibility from the start since it was implausible. To make matters worse, the FCC lied to Congress and denied FOIA requests for documents proving that the hack occurred.
