site erased or hacked??

Yesterday i was going to update my website when I realized that it's all gone. Only an older version of the homepage remains - strangely enough one that says something like 'site is being updated'.
When i logged into my indexhibit edit section, all the sections are gone as well. Have I been hacked? Or could the pb be related to some new updates from the company hosting the site? I've had this site since 10 years... please help me?
here's my page:

could it be related to my host updating to a later php version?
im on indexhibit 2

And what does your host say...?
