What would you like to do?
"iframe" sitedown fallback via <object>
<!-- so it turns out that the object tag can act like an iframe
but the cool thing is you can nest object tags inside eachother for a fallback path.
what this means is you can "objectframe" a site.. and if it fails.. (site down, offline, whatever).. it'll use the next one.
so you can objectframe the live site and fallback to a screenshot.
or something.
demo at : http://jsfiddle.net/paul/CY2FQ/1/
-->
<object data="http://thisurlwillfail.sohard">
<object data="http://paulirish.com">
<object data="/images/screenshot.png"></object>
</object>
</object>
<!-- this could probably work in IE with some classid bullshit
http://intranation.com/test-cases/object-vs-iframe/
also in this case there can be an ISP that intercepts your failed DNS (which fucks it up) but in most cases a site timeout wont trigger that so it'll be ok. :)

It should be noted that if you are using privacy extensions (like ScriptNo) those things referenced as "objects" will have to be whitelisted, just like you would have to white-list third-party cookies, tracking scripts and other off-site material.
