Here is an alternative I wrote that seems to work flawlessly.
<script type="text/javascript">
var bIsOnline = false;
(function() {
var anImage = document.createElement("img");
anImage.onerror = function() { bIsOnline=false; }
anImage.onload = function() { bIsOnline=true; }
anImage.src="http://www.quirksmode.org/pix/logo_quirksmode.gif?" + (Math.random()*100000 << 0);
})();
function test() {
alert("You " + ((bIsOnline) ? "ARE" : "ARE NOT") + " online")
}
</script>
<body onload="test();"></body>
