CDN problem

Hello,

do you guys having problem with loading CDN? I am trying to access website coursera and I notice the CSS, javascript files e.g https://dw0ugk4msqulk.cloudfront.net/c125b14c9a359e3a92f0e2077eacc19f5d689515/js/vendor/jquery.v1-7.js could not be load and when I asked my friend on the other network not Telstra to access it at the same time it works perfectly fine.

any clue?

Thank you,

Surya
