Thanks for the comment, yes you’re correct that this is not working. I don’t think a AAAA record for the domain root is necessarily required for blog to work but it should certainly have one and that was an oversight.

The real problem is that I haven’t been able to test it properly, as my home network’s ipv6 is currently broken despite working during ipv6 week earlier in the year. Compounding this is my lack of time to sit down and fix it :)
