To speed up the load time of our site, we defer the loading of some scripts. This has been working fine until a couple of days ago. I've boiled the issue down to this short page of HTML.
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">

<script type="text/javascript"

<script type="text/javascript">
//<![CDATA[
var scriptUrl = "http://ads.trafficspaces.net/v1.22/adservice.js";
jQuery
.getScript(
scriptUrl,
function () {
alert("I'm never called")
});
//]]>
</script>

It would appear that the script in question is served with a text/plain content type. I'm not sure what it was before the weekend. Could this be the problem?
Looking in Fiddler, it appears the request is never made, but I can fetch it when I paste the URL into another tab. If I change scriptUrl to one under my control, it works fine. What's going on?
