This happened due to the lack of a MIME type. I was mistaken in both environments using IIS7; The QA server uses IIS6. We added application/x-font-woff to the IIS configuration and fixed it.
UPDATE: Add this to your Web.config to link the .woff files to the correct MIME type so that the server knows what to do when such a file is requested:
<configuration> <system.webServer> <staticContent> <mimeMap fileExtension=".woff" mimeType="application/x-font-woff" /> </staticContent> </system.webServer> </configuration>
