IIS will not server .woff
files by default, so in IIS you'll need to add a <mimeMap>
entry to your web.config
file;
<?xml version="1.0" encoding="UTF-8"?>
<configuration>
<system.webServer>
<staticContent>
<mimeMap fileExtension=".woff" mimeType="application/x-woff" />
</staticContent>
</system.webServer>
</configuration>
