On March 1, 2018, Comcast customers could not reach the Germany-based encrypted email service, Tutanota, using their Comcast broadband connections. According to Zack Whittaker, writing for Zero Day at ZDNet…
Starting in the afternoon on March 1, people weren’t sure if the site was offline or if it had been attacked. Reddit threads speculated about the outage. Some said that Comcast was actively blocking the site, while others dismissed the claims altogether. Several tweets alerted the Hanover, Germany-based encrypted messaging provider to the alleged blockade, which showed a “connection timed out” message to Comcast users.
It was as if to hundreds of Comcast customers, Tutanota didn’t exist.
But as soon as users switched to another non-Comcast internet connection, the site appeared as normal
The outage is activating advocates for net neutrality because it seems like Comcast was blocking a website that it didn’t like. Or it could be a technical glitch between Comcast and Tutanota. This happened in 2015 when HBO launched HBO Now, the standalone service that does not require a multichannel video (“cable-TV”) subscription. (Comcast is the largest multichannel video provider and distributor in the United States.) The outage prompted an outrage from Comcast customers who could not access HBO Now’s and accused Comcast of acting in bad faith. It turned out to be a technical glitch involving DNS.
That 2014 HBO Now incident and this recent Tutanota outage underscores the reasons why we need net neutrality. Without it, the Internet can’t operate as a bona fide communications network and can block whatever site they see unfit. In the United States, broadband Internet is monopolized by a small number of companies, and the broadband oligopoly creates distrust between consumers and Internet service providers. Net neutrality is not just good for the broadband customers but also the companies who run these networks.
