font changes in twenty eleven not working consistently

I am working out of twenty eleven theme and trying to change the font for all areas of my website. I have added the @fontface rule to my css and changed the font family as well. The updated font is reflected on some computers in my home as well as mobile devices, but does not come through when I check the website on other computers. I have read through other troubleshooting posts and have not been able to find/fix the issue. Thanks in advance!

Website is http://www.majormotionmedia.com. This is the code I currently have:

@font-face {
	font-family: 'Compass';
	src: url(http://www.majormotionmedia.com/wp-content/themes/twentyeleven/Compass.ttf);
	font-weight: normal;
	font-style: normal;
}

body, input, textarea {
	color: #373737;
	font-family: 'Compass', sans-serif;
	font-weight: 300;
	line-height: 1.625;
}
