Officially they still don't offer 10Mb upload on cable. My cCable package still says "Up to 30 Mbps Down / 2 Mbps Up" on their website. The 10Mb upload is something being offered by Cogeco across their entire footprint ahead of TSI mentioning anything about that.
To confirm, there hasn't been anything officially released for Cogeco on the 10 Mbps up speed for TPIAs. They may be doing some testing on TPIAs (which RizzleQ is a lucky one since I don't have 10 up at home yet! :P ) Once we do have something official it will be communicated to our customers.
