Hijacked

I am not sure but I think someone has hijacked my domain. when I go to my domain there is already a web page there and I dont know where it came from. Any help on what to do?

the site is www.azdesertgems.com
I registered it in aug and had a under construction page up.

Thanks

Just a misconfiguration. I’ve fixed that for you; apologies for the inconvenience.

Thank you …it had me worried for a minute.
