Located in Michigan, using Comcast with a 170Mbit/20Mbit connection. According to that test page:
CDN POP location: Beauharnois, CA
Speed: 86.23 Mbps
I've also attempted downloading over a VPN located in various locations (Canada, west/east coast US, etc), and still the same speeds (~300KB/s) most of the day. No peering or transient gateway issues (or packet loss) from my connection, to the download server. Each time I have a pretty consistent ~35ms or lower ping as well. Surprisingly, right now I've just tested downloading, and I'm getting about 12MB/s+. I most definitely am not getting those speeds around 2-5AM EST.
