What do you mean by "disappeared"? Did the page just go white/black or something?

I didn't experience that while reading the article (waterfox browser), and can't recall that ever happening on Wired, and I somewhat frequently read wired articles (few times a week, not a registered/paying member).

I tried it in chromium (no extensions) and if you scroll there is a fullpage ad where the article seems to "disappear" but it's essentially an ad fold, and if you keep scrolling the rest of the article is there. Otherwise not sure what you mean? What browser you using?
