If the author of the blog is reading this, the site seems to be unavailable from my location on the Shaw Canada network. I thought it was down, but it appears there's some sort of network error preventing my packets from making it from here to there. This happened on the previous (and very interesting) article as well.
Back in the day I had similar problems, but I used a different Canadian ISP. The issue was their DNS: for some reason it did not resolve some valid domains.
Switching to Google's DNS might fix your problem. If it doesn't, it's probably Shaw's routes.
Nifty! I'm on Access (a small regional ISP in SK), but traceroute indicates that the packets are disappearing at a Shaw router in Calgary. Looks like Access gets its connection from Bigpipe (Shaw's bulk offering).
