Answer 1

In your JQuery ajax call, you could use the following and then query the status code of the error. Note that the status code will be 0 if they are offline, but you can also query other status codes (see below for a list):

$.ajax({
    //your ajax options
    error: function(statusCode, errorThrown) {
        if (statusCode.status == 0) {
            alert("you're offline");
        }
    }
});

Here's a list of status codes you could also catch for reference: http://support.google.com/webmasters/bin/answer.py?hl=en&answer=40132
