Why is my Github-hosted site responding with HTTP 302 instead of 200?

Question

I own the domain penkov.id.au. I host a blog using github, with an A record for the subdomain michael.penkov.id.au pointing to the github pages server (204.232.175.

Answer 1

Here's what I heard from github support:

The A record pointing to 204.232.175.78 is what's causing the 302 redirect.

Replacing the A record with a CNAME (pointing to mpenkov.github.com) in my DNS settings fixed the problem.

For reference, here's what my DNS record looks like now:

misha@misha-antec:~$ dig michael.penkov.id.au +nocomments +nocmd +nostats

; <<>> DiG 9.8.1-P1 <<>> michael.penkov.id.au +nocomments +nocmd +nostats
;; global options: +cmd
