The title basically says it all. If you're participating in the Internet-Wide Day of Action for Net Neutrality and planning to use one of the widgets on your website or blog, or help drive traffic on social media or from a Twitch, Vimeo, or YouTube channel, I strongly encourage you NOT to point people directly to the FCC.gov website.
My organization, Fight for the Future, has been involved in raising awareness about net neutrality since before the last round of this fight in 2014-2015. Together with our partners we've helped deliver millions of comments to the FCC. Over the years, we've seen the FCC website crash repeatedly under even moderate traffic. More recently, they claimed they experienced a DDoS attack at the exact moment that large numbers of people would have been attempting to comment following the John Oliver segment.
The fact is, the FCC's site just isn't reliable. If you want to make 100% sure that your comment will end up in the docket, use one of the sites set up by public interest groups that store and queue comments to ensure that they get submitted even if the FCC's site crashes.
Here are two options: https:/www.battleforthenet.com — run by the broad coalition behind the July 12 day of action, also allows users to call and email their lawmakers, which is an important part of the strategy for winning net neutrality. https://dearfcc.org/ — run by our friends at the EFF.
If you want to build something yourself, that's cool too, but the bottom line is if anyone points significant traffic at the FCC's site on July 12, it will probably fall apart, so use one of these resources instead to make sure that every voice gets heard.
