Typekit is one of the easiest ways to get fancy fonts working on your website. Just sign up for an account, pick a font and paste a few lines of code into your pages. TypeKit takes care of the rest, ensuring that your fonts load and there’s no unsightly flash of unstyled content (FOUT) or other problems.
There is, however, one possible problem with the default way of embedding Typekit fonts. If the TypeKit code fails to load, it can slow down the rest of your site. Typekit avoids FOUT by pausing your page load for a fraction of a second, but if the Typekit script never finishes loading, that fraction of a second can turn into many seconds. While Typekit has excellent uptime, let’s face it, outages happen, and we understand if you don’t want to hang your own site’s fate on another — via Webmonkey
