Do you know what his blog infrastructure is? Over 3 hours later its still not working. Git is decentralized and can and does scale. Builds can be spread across multiple machines on EC2.
From 2003 until a few months ago, I hosted my website off of a Pentium 2 in my apartment. Behind slow DSL, no less.
Once my blog posts started reaching hacker news I thought "Oh, I'll just move site out of the apartment and into the cloud!" and bought an account at prgmr.com (which I highly recommend, by the way).
However, I serve WordPress via Apache on a 256 MB VM, which clearly thrashes under load.
Tonight I will purchase an upgrade to 512 MB of RAM and play with nginx.
I'm sorry for the inconvenience.
p.s. I do have WP-Supercache enabled and a PHP bytecode cache. I _could_ just host at wordpress.com, but I might as well learn nginx while I'm at it...
