There are a number of reasons why IE9 may not render this font.

IE9 will not download a cross-domain font as a security precaution.
There may be something like a proxy (or security software) stripping the "Access-Control-Allow-Origin" from the header.
Settings may prevent the download of fonts.

For the IEs, this will be limited to IE9+

Of course a different browser will most likely work in this case and likely the most reliable from this aspect would be Chromium.

However, the first step in anything is to clear cache!

It must be ensured that the EU is in possession of a full and current set of files. Most people know that IE does not always do what er expect it to do. In fact, most people have stopped using IE now. For any other browser a cache clear is a cache clear. For IE, you may have to do this up to 5 times just to be sure. It also helps if you set your request properly. There is no point clearing everything other than what you want to clear!

For many, this may work. Job done and end of story.

Keeping more along the lines of trouble-shooting this type of issue, the next step for the EU is to press F12 on the keyboard and see if there are any error messages. Error messages will guide as to where to look for the cause of the problem.

Please don't get me wrong here. I do have an issue with there not being a fail-safe in place here in case of issues like this.

It is a normal every day issue with any static content, which has been changed. The first step is to try a hard refresh (Ctrl+F5). No fix? Clear cache. No fix? Read the manual! Check your settings. Trouble-shoot your browser and security software. Only then should the source be contacted and provided with all the relevant information. Do not expect the recipient of a trouble ticket to be clairvoyant. Do not expect the recipient of a ticket to be willing to help you, if you show no sign of being willing to help yourself. Do not lose the rag with the person you are asking for help because it is not likely to be their fault.

If you want help:

Write a clear and concise subject line.
Operating System (include any service pack).
Browser and version.
Link to where the issue was observed.
(possibly: What you did immediately before.)
Clear and concise description of the problem (and keep opinion out of it!).
List what you have already tried.
(if likely to be relevant: List your security software.)

I really hate to troubleshoot for IE because it is much more simple to use a better browser. Let's face it, just about anything is better than IE. Carrying on from the above ...

Press F12 (Developer Tools) and look for error messages as these may guide you where to look.
Open your options panel and look for any signs of font downloading being disabled.
Try temporarily lowering your security level.
Try compatibility mode.
Staying on the one page, briefly disable your security software and retest.

Above all, if you do not know how to work with your options panel, what the heck compatibility mode is or what developer tools are, Google them! It's your browser, which you are choosing to use. Learn about it!
