Why is HN so Slow Lately?

Has anyone else noticed this? At first I thought it was just a quirk in Safari on my iPhone, but I am seeing the same slowness on my work PC as well as at home.

HN is taking an average of 13.51 seconds to return from the initial GET request for a new page (over ten attempts, ~28KB / request). Every subsequent request is in the noise. It's making browsing the site tedious to the point where I hit "Next" and go to another tab.
