Error checking on external JS file

[admin]

Here's the problem.

A 3rd party provider has the ability to track our Pay-per-click campaigns. To do this, we must include a call to an external JavaScript file.

Occassionally, the server where the external JavaScript file is located is down or inaccessible.

Is it possible to add some error checking to the JavaScript code that calls the external JavaScript file so that if the file does not load it does not crash your webpage?

Thanks,
