I started noticing a drastic reduction in my download speeds (around 600Mbs) versus closer to 1000Mbs. I'm wondering if something happened recently at one of the boxes on the side of the road, because I did notice what looked like a Comcast box tipped over on Jericho road between Lemoncreek and Hinchman.
