There is another thread posted as well, for the same issue. Seems to be a few of us experiencing it. I originally tried clearing cache and a dns flush, with no effect. I've tried on a desktop and a laptop and experienced the same results. I just tethered one of my laptops and it ran perfectly smooth on LTE. It seems to be ISP related.
