I am concerned about the reliability and speed of hosting fonts on third-party servers. How does it work?

TPTQ Arabic hosts fonts on a global content delivery network using Amazon.com’s redundant server architecture. This makes TPTQ Arabic webfont hosting faster and more reliable than most of our clients’ own websites.

Because browsers have limits on how many simultaneous requests they can make to individual servers, hosting images or fonts on third-party servers will utilise more connections, loading files much faster than if they were hosted on the same server.
