Qwertee is an online store for t-shirts that offers new designs every 24h. Normally there is a countdown at the top of the page. However, this countdown does not exist with LocalCDN because "Hogan.js" does not exist.
According to the source code https://cdnjs.cloudflare.com/ajax/libs/hogan.js/3.0.2/hogan.min.js is requested.
However, this library is almost 7 years old and far from up-to-date, moreover it seems to be something from Twitter itself. Not sure if this should be integrated.
