I am using google font on my site. Some clients in china said that the site load very slow. I checked it, it is causing by the google fonts. I looked the google font faq, they said it will download the font file to the customer's computer before loading the site. Are there any way to fixed this slow loading issue?
This was a known issue... Google Fonts were slow loading in China. Previously you could serve mirrors of the fonts through Qihoo 360 CDN servers in China. However, as of August 2016 the problem has been fixed. At the same time Qihoo 360 has stopped fonts.useso.com and all mirrored fonts hosted under fonts.useso.com stop working now. Details are described here.
Google has fixed Google Fonts, which now directly serves the css and font files from Google’s servers in Beijing, which means Google Fonts are much more stable and faster to users in China now.
I recommend all webmasters who have been using fonts.useso.com switch back to the original Google Fonts as soon as possible.
I figured a way to fixed it. Instead of loading it with link tag, I changed to load the font with javascript and load it async, it is fine now. much faster
