Amidst proposed rule changes from the Federal Communications Commission around net neutrality, late night host John Oliver urged his viewers to tell the FCC that they support strong net neutrality rules.

This isn’t the first time that the Last Week Tonight host has pushed viewers to contact the FCC about net neutrality. About three years ago when the FCC was considering introducing rules that would end net neutrality Oliver urged viewers to give the FCC feedback on the rules, as a result of the influx of comments, the site crashed. The rule didn’t pass then and the internet remained the same equal playing field but now net neutrality is under attack once again.

The Open Internet Order that was passed in 2015, was intended to provide an open internet with an even playing field for all for 20 years, but the FCC chairman Ajit Pai wants to roll back this provision, called Title II.

What is net neutrality?

Net Neutrality or “Open Internet” refers to the idea that no website gets prioritization over another due to blocks, “slow lanes and fast lanes” or paid prioritization imposed by your internet service provider. This essentially means that your ISP whether it be Verizon, Comcast or another provider can’t slow down your access to certain sites to prioritize sites that pay them a premium or fee. Meaning you’re free to use any website you like at the same speed as more popular sites.

The FCC and chairman Pai, a former general counsel at Verizon, are considering repealing the provisions that protect net neutrality. But they’ve asked the public to chime in on the issue before a vote scheduled for May 18. Oliver urged viewers to do exactly this during his show Sunday night after detailing the issue and giving a history of FCC net neutrality rules.

Last time Oliver did this, the FCC website was overwhelmed by the traffic and crashed due to the influx of commenters. This time around they’ve made commenting more difficult to get to. So Oliver made a site to streamline the process called that brings users right to the section where they can comment on the issue. Once on that page all users have to do is select “express” and write their message to the FCC regarding Title II and net neutrality.

Following Oliver’s segment, the FCC website crashed once again. Those trying to comment on the site took to Twitter to express their thoughts as well.

The site was back up and running Monday after the brief crash but the link was no longer directing users to the comment page. The FCC reworked the site so that users would have to do some digging to find the new comment page.

From the FCC homepage users can select “file a public comment” a list of popular proceedings should come up, there the act should be the top one, with more 52,000 comments so far. The site seemed to still have some residual issues though, with the list of popular proceedings only appearing. If you can get to the page to express a comment, the proceeding number is 17-108.
