Hey ya'll. This is (really) Chris Coyier. I had css-tricks.com registered on GoDaddy. It recently came to my attention that the ownership of this domain has been transferred away from my ownership to PlanetDomain. For now, thankfully the nameservers still point to MediaTemple, so the site is still up. That could change at any time.

I'm going to keep track of all this.
Timeline of Events

Friday 7:30am - I found out about all this from emails from David Appleyard. I immediately thought of David Walsh who this is also happening to. It's also happening to instantshift.com and sohtanka.com. None of us share a GoDaddy hosting account. These are all separate instances. Important to note: I received no email or phone call verifying the transferring of this domain. The email address in my GoDaddy account was unchanged.

Friday 7:45am - Called GoDaddy support at (480) 505-8877. Was not helpful. Was told just to email domaindisputes@godaddy.com (which I did immediately).

Friday 8:06am - I tweeted about the problem. GoDaddy sent me a DM saying to fill out a form, but the form was a 404 page.

Friday 8:30am - I got the correct link to the domain disptute form and filled it out. This included a scan of my driver's license. The website says it will be 3 days for an initial response. I hope it's sooner than that.

Friday 9:00am - I went to my banjo lesson because at least nobody can take that away from me.

Friday 10:10am - Trying to contact PlanetDomain (just assuming this is them). They don't seem to have an active Twitter account. Just sending an email through the contact form for now.

Friday 10:15am - Got generic email back from GoDaddy:
We have reviewed your claim and we will contact PlanetDomain and request an FOA (Form of Authorization) for the transfer. If their records also show the same registrant at the time of transfer, we will work with them to see if they can transfer the domain name back. However, they are not required to transfer the domain name back.

If they are unwilling to transfer the domain name back you will need to contact the current registrar or registrant for further assistance.
Other News

    This happened to David Airey as well. He attributes a Gmail Security Flaw as to why he was never notified of the domain transfer.
    November 21st was the last update to my sites WHOIS data. On that day, I had a minor site hack. VaultPress caught it. In my index.php file in the root (effects the entirety of WordPress) a link was added to 8oc.com. This same thing happened to Kirupa Chinnathambi of kirupa.com.
    David Walsh received two emails on November 28th from moya.server@gmail.com. One said: "trust me godady can't help you," the other: "pay 2k to get ur domain back .."
