My modem has a current up-time of around 26 days. Up to yesterday the error counts, both corrected and uncorrectables were all zero. Today, there is this:

I'm not seeing any issues, so I don't think it's anything to really worry about. But I'm just curious why after over 3 weeks of no errors, these appeared within the space of abouit 12 hours.
It could also indicate that a repair crew is working on lines somewhere between your home and the head end, or as reds91185 said, that a connector somewhere has loosened and the cable is flexing.
And if it is a loose connector, then that's also upstream of me. The only connector between the line drop and the modem is the earth barrel, which is in the crawl space under the house.
So, since you agree that there IS a connector on the grounding block (two actually), when the weather clears and you can get down there with a 7/16" wrench, visually inspect both of them for fit and corrosion, then retighten just beyond hand tight. Electrical code requires the grounding block tied over to the power ground line, not just a barrel connector.
I'm in SoCal, the weather is (nearly) always clear.
The connector was re-checked a couple of months ago when it looked like I had another issue and is clean and tight. And yes, it is connected to ground.
Ha. Now I can't even get to the status page.
I re-booted my modem, at the request of support on an unrelated issue and now my browser just sits and spins trying to get to the status page and eventually times out.
From the server connected directly to the modem I can't even ping 192.168.100.1 anymore. I get 100% packet loss.
Everything else appears to be working correctly. It's an Arris SB6183.
Those symptoms typically indicate a DHCP addressing problem on your home LAN. Connect your desktop or laptop computer directly to the modem using a CAT-5e cable into the modem LAN port. Don't try to use your router, a separate server device, or a WiFi conection at this point. If Windows (or your computer's alternate OS of choice) complains that the LAN connection is not working, tell it to repair the LAN connection.
