Hiya guys. I misconfigured my DNS when I moved the blog here, resulting in a CNAME record (i.e. “The named server is actually on this domain name over here”) pointing to Google rather than a MX record (i.e. “The named server’s email is processed by Google Apps, please send mail to him there”). As a consequence the http://kalzumeus.com alternative for accessing the blog is going to be down for about a week while the TTL for that record expires. Fun stuff, DNS, fun stuff. Some places on the Internet might see it earlier than others.
I’ve told Google to redirect the domain on their end (search for Google Webmaster Console) but that will probably take a day or to to take as well.
Sorry for the mixup! Thanks for those folks who mentioned it.
