App developer Panic Inc. knew it had a network problem when customers began complaining about trouble downloading and updating Panic apps.
“Geez, your downloads are really slow!” was the common complaint that started coming in a few months ago, Panic co-founder Cabel Sasser explained in a blog post titled, “The Mystery of the Slow Downloads.”
But once the mystery cleared up, it all made sense. Panic and its users were the innocent victims of a longstanding network interconnection battle between cable ISP Comcast and Cogent, which operates a global network that carries traffic across the Internet.
