Check MyServices to see if they really did upgrade you.
Also, look for "Resetting the cable modem due to docsDevResetNow" in your event log at or around the time you called. That would mean that they tried to reboot your modem and if the new speeds didn't take hold then it could mean a few things. I saw that in mine when i called and knew something was wrong when i was not getting the new speeds. that and my internet stopped working till evening time when i had to call again.
MyServices reports I have "Ultimate 75 Upgrade" on top of Standard Internet.
Tier 3 said to wait 24 hours for the provisioning to roll out but that seems a bit odd, and a bit less believable now that the speeds are no higher than 25Mbps about 8 hours later.
We'll see tomorrow.
