AdWords Conversion Tracking safe if googleadservices.com unreachable?

Would like error checking code

[prubin]

Hello. I'm concerned about adding the AdWords Conversion Tracking javascript to an order placement page. I'm wondering what happens if for any reason googleadservices.com is unreachable by the customer? Is the javascript simply ignored by the browser, or does it throw an error of some kind? This would be particularly bothersome when a customer is placing an order. Perhaps there's a way to put a conditional statement in the javascript code to prevent javascript errors when googleadservices.com is unreachable?

Usually I beleive those javascipts, if they fail, stop the rest of the page from being rendered. This is why they always advice to put the scripts right before the closing body tag, so even if it does fail the page still renders. So put it right before the </body> tag and you should be ok
