Last week, with out my prior knowledge, Posterous changed how they handle sub domains pointing to their servers. This means if you had a blog address, namely blog.douglasmkelly.com – all of a sudden your domain wouldn’t resolve to a site. My blog, over on Posterous, effectively went down. No email was received. There was no popups or alerts on their site. When they changed their IP address about a year ago, there was an email a week telling bloggers Posterous’ old IP was going away. So here I am stuck researching how to fix this, as I’ve listed the blog in my email signature block.
I have a registrar where I ordered my domain name service (DNS) that points to my virtual server. I had an A record pointing to the IP that Posterous lists on their help section. Then on April 11th or 12th or shortly thereafter, my blog stopped showing up. You can’t even go there by using something like posterous.com/DouglasMKelly!! Posterous was recently purchased by Twitter. I’m not saying that they’re the cause, but they’re the 2nd largest social networking site – And they can’t tell everyone they’re changing their practices? Finally today, I located a help document on how to do a sub domain – one has to point a CNAME record to posterous.com. It’s very easy. There’s an article on Posterous’ site. Let’s just hope that it works. I’ll comment/update when/if everything resolves correctly.
I’ve spent the last few days changing A records on both the registrar’s site then my server and back to the registrar. Thanks Posteritter. Changing from an A record to a CNAME is easy, but does take some time for the DNS servers to update. MEH.
