Alright, I caught a crash in midstream and grabbed some screenshots. I started losing connection at 2:40 PM ET and saw two error messages in the log and then the upstream signal died. The modem then became unresponsive for a minute or two before finally reconnecting upstream with a bunch more error messages around 2:42.
