Here in China there is something known as the "Great Chinese Firewall", so if I suffer any problems it's usually caused by this, or, the sheer number of folk using the internet here. I Modeller is one easily the best site I use, both for speed and for ease of use. I occasionally get a blip, but I'm sure it's caused by something here, and nothing to do with your site. The only weird thing I've experienced is that I've got a message when I've posted a comment saying that this is a dual comment that has already been posted (maybe I've clicked the mouse too many times?), other than that, i modeller is the dog's b-l-o-c-k-!
