Since link update, Academicons do not work.
Dear JP Walsh, 

Apologies in advance for this is my first ticket. I have a website built in Rmarkdown which was online for a month. I updated a typo (and nothing more) a few hours ago and the academicons disappeared. You can see it here (https://icsmp-covid19.netlify.app), at the footer, that now it only displays empty squares instead of Academicons. I am 100% sure nothing else change as I have checked the GitHub App log. Before, I used it like so.

/* Academicons */
<link rel="stylesheet" href="https://cdn.rawgit.com/jpswalsh/academicons/master/css/academicons.min.css">

I saw in your Github you updated the link, so I substituted the above link for:
https://cdn.jsdelivr.net/**gh**/jpswalsh/academicons/css/academicons.min.css 

Thank you very much!

Best,
F/
