I'm having the same issues guys. We're working on it and hope to have everything solved by the end of the day. This isn't a security thing. Not sure exactly what it is but the guys are on it. Thanks a bunch.
Had the same problem over at HN until today. Not sure what the problem was, but they made some tweaks and the site loads faster than ever now. Also, for as long as this site is running slow: just refresh the page, and it should load right away.
I finally got tired of it and installed adblock. Problem solved.It's been really bad this afternoon
