When I created this blog a couple of years ago, I was disappointed to find out that the GitHub Pages service (GHP) did not support IPv6. This was due to the fact that GHP’s CDN provider Fastly didn’t support IPv6.

To work around this problem I ended up inserting a dual-stacked HTTP proxy service in front of my (IPv4-only) GHP-hosted blog. While it was hardly ideal, it did the trick.

The other day I was pleasantly surprised to find out that I no longer need this hack: Fastly and GHP now do support IPv6! IPv6 appears to have been enabled for https://toreanderson.github.io and all other GHP sites without requiring explicit opt-in. Perfect!

When did it happen? Well, it seems Fastly announced IPv6 availability on the 31st of March (after having had it in limited beta since last summer). Assuming Twitter is a reliable indicator, IPv6 was enabled for GHP specifically sometime between the 10th of April and the 28th of May.

I was quite critical of Fastly in those old posts, so it’s only fair that I congratulate them now. Well done, Fastly - I’m very happy to see you get on the IPv6 bandwagon!
