Feb 15 lost SharePoint

Monday morning, Feb. 15 about 10am CST, I was working in SharePoint but lost connectivety. When I try to log in, I get a message:

HTTP/1.1 200 OK
Server: Microsoft-IIS/7.5
Date: Fri, 26 Feb 2016 19:29:31 GMT
Connection: close

The date changes every day. I'm afraid the site was deleted and am hoping it can be restored. Help?
