I don't think it's an issue on your end because I faced a similar issue recently and knew right away that it was an issue on their end since all other sites were loading quickly with zero issues.
Seems to have completely resolved for now, but they need to minimize such major issues since they are still in the infancy stage.
That's a cookie and cache related issue and we have discussed it before in this thread. We really don't know that if this issue is from MonkeyTlit's end or from our end but surely this issue happened with some users and once those users cleared the cache and cookies of their browser, the site loaded without any further issues or problems.
