It sucks. Their entire CDN is slower than a 300 baud modem. It keeps breaking websites and we can’t block it because it’s used mostly for themes. It makes browsing your site a bad experience and in many cases makes sure we don’t go back again.
The solution is simple: download the files you’re using and link to them locally. Tada! No more lag, no more delays, no more browsing problems. And it only takes a few seconds to ensure your visitors will get a better experience.
P.S. Yes I realize the point of the CDN is to load faster, but when a CDN is that bad and slows down your site, perhaps it’s time to rethink their claims about their CDN.
