Why is Comcast upgrading my modem software in the middle of the day?

My internet connection dropped multiple times this morning and my wife was complaining she was getting kicked out of her online meetings. I logged into my cable modem, a Motorola MB8611, to see if I could see if this was a local problem or something that covered a wider area (no complaints on Nextdoor that I saw).

Checking the Device Information page, I was surprised to see the modem software version had jumped up several versions and there was a new feature, a spectrum analyzer. I was intrigued by having the new version after over a year with no software upgrades. Maybe it would fix the loss of bonding on the downstream channel that keeps happening every week. And I use spectrum analyzers for work and it would be interesting to see what the signals on the Comcast cables look like.

But just a few minutes later, my Comcast connection dropped and my modem reset. I logged back into my modem and was disappointed to see my modem software version had changed again to something slightly older than the version that I had for the past year. What?!?

So I'm curious as to what is going on? Were all the modem resets and lost connections an attempt to upgrade my modem software that didn't work? The software version rollback is a classic symptom of an upgrade failure (Not criticizing. I've had my share). Will I get the spectrum analyzer feature back?

And why couldn't this upgrade be done at night instead of the middle of the day?
