That is an interesting coincidence, because around the time of your post, I was having a similar problem on a couple of other sites (techmeme and recode). The pages loaded OK, but were completely blank.

Same here. I don't think it has to do with HN traffic since Arment's blog is often on the front page.

Doubt it; his blog is a static site.

I got that for a few minutes too but it started working again.
