If you go to the testing page (http://www.singlehop.com/why_singlehop/data_center_details.p...) you have two choices for testing locations - downtown leads to https and goes fast, but elk grove leads to http and is uncompressed.
Given how easy it would be to get caught doing this (the https download makes chrome claim 40mbps over a T1) I think it's more likely this was accidental.
