I am using GreenGeeks as a host. So I guess my next step is to talk to them? Its been over a week with this problem. I cant imagine its an upgrade.
Definitely.
I can not imagine the site is not actually working for one week. If they do not respond, move to any standard web host.
For any web host, if there is definite server problem or the server is down more than 5 minutes, always let the webhost know in case of managed VPS and shared. For unmanaged VPS (for example your situation) you have to do the server side works, but for these things usually all standard host helps despite being unmanaged.
