I don't think it is so much that they oversold the "bird" as they have oversold the gateway capacity where your signal is "administered" on the ground side of things.
Now there does seem to be some "tweaks" that they can sometimes apply to improve things, other times a plan level change will result in you being assigned to a different and hopefully less saturated gateway.
They are adding capacity but it is a slow and tedious process.

It is my version of "SCC Lite"
It outlines some of the useful information in the modems internal "pages". They are in order of "depth" I guess you could say.
I would suggest you download then into a folder on your computer for a reference at the times your system my be down.

First some prelim text:
Open the Modems SCC by entering 192.168.0.1 into your browser opens the Main Page.
The Main page is a sort of "at a glance" system check:
Data Allowance is shown in one area
In the area marked as #1 an Icon gives indicates System Status by color:
Clicking on the words System Status will open a more detailed page.
Useful information here includes Signal Strength, LAN Status and your assigned Gateway server.
In the area marked #2 an icon indicates System Information status by color:
Clicking on the words System Information will open a more detailded page.
Useful information here includes modem software version and Beam and Gateway assignments.
Clicking the smaill icon marked as #3 will open the modems advanced pages.
Here you find a list of present and past "errors" or conditions experienced by your system.
Some what deeper into the advanced pages is where we can "toggle" Web Acceleration in the event of page "timeout" problems or perform a MBX Reset.

Those pretty much touch on the main areas
