Asp.Net CDN Minified JQuery Not Gzipped?

Does anyone know if there is a reason why the minified versions of the jQuery files on the Asp.Net content delivery network are not gzip compressed? The non-minified v开发者_开发问答ersions are properly compressed.

Examples:

http://ajax.aspnetcdn.com/ajax/mvc/3.0/jquery.unobtrusive-ajax.js (GZipped) http://ajax.aspnetcdn.com/ajax/mvc/3.0/jquery.unobtrusive-ajax.min.js (Not GZipped)

If I look at the Google CDN, the minified files are also gzipped. Unfortunately they are not offering jquery.unobtrusive-ajax, jquery.validate, or jquery.validate.unobtrusive.

My FireBug sees them (both) gzipped:

Are you behind a proxy? At work our proxy rips out the compression on some files before it reaches each client

Not sure what was going on, but now the files are showing gzipped. As mentioned in one of my comments, it seemed to change when I went from one I.P. to the other.
