I did some tests and it appears that either my account has not been targeted for the speed upgrades or my area has not been enabled yet.
Added to that, it is amusing at how Spectrum’s own employees had no idea about the speed upgrade, with the support rep telling me that 35 is the max upload speed capable on Spectrum’s network.
Regardless, I maxed out my upload connection uploading some files to a remote server on a 500/500 connection and the max I was getting 35mbps from my Spectrum Account.
