      Many Americans don't have access to home broadband. This is true even in this study of the 50 largest metro areas! https://policyinformatics.asu.edu/sites/default/files/%5Bterm%3Aname%5D/%5Bnode%3Acreate%3Acustom%3AYm%5D/d_msa_figures.pdf …pic.twitter.com/1wQuu1j5bw

      Google Design's "Best of 2019" page is 64MB, takes 98s to load the "2019" that's the main visual element above the fold (from a Cable modem in Australia). https://webpagetest.org/result/191230_TP_be737ced75c39478259d0200bcbf7fc9/ …pic.twitter.com/BGAhqVArtd

      Waterfall graph of page loading. The giant above the fold gif is the first thing to start loading, but it's overwhelmed by the other huge gifs that load in parallel.
      Timeline of page updates, it's 98 seconds before the above the fold gif goes from showing the top half of an outline of "2019" to all of an outline "2019".

          Google's page announcing its use of AV1 in Duo is 58MB. The announcement shows off a video encoded at 30kbps. 58MB @ 30kbps is enough for 4.3 hours of video. https://webpagetest.org/result/200422_Q8_816f4200a6d31b40694deedbaa19dfff/ …pic.twitter.com/CS0B0XFcSq

          Waterfall plot from https://webpagetest.org/result/200422_Q8_816f4200a6d31b40694deedbaa19dfff/1/details/#waterfall_view_step1 showing individual gifs that take 60s to load, total load time > 100s from a cable modem in Australia
          "Side by side comparison of an incoming video call at 30kbps with our new AV1 (AOMedia Video 1) video codec technology on the left."

          Cool! Am I hitting some cached CDN assets that haven't expired yet or is the page now 39MB? https://webpagetest.org/result/200102_P3_84c38f74a597d3f5f67b64f1afbacfc5/1/details/#waterfall_view_step1 …pic.twitter.com/fpkOWe8HYC

          Waterfall plot of page load. Some assets seem much smaller, others seem to be roughly the same size as before.

      Loading seems to be taking a while.

      Twitter may be over capacity or experiencing a momentary hiccup. Try again or visit Twitter Status for more information.
