Recurring outages late at night
Last night around 3AM (PDT) my Internet service abruptly went out. I tried rebooting my modem and router and no effect: the "US" LED on the modem just kept blinking. I could ping my router and the local network side of the modem, but not 8.8.8.8. This is a recurring problem I'm experiencing: very frequently when I'm working late, my Internet service goes out for hours, and then returns by morning.
How do I track down the cause and stop the disruptions? Could it be from scheduled maintenance or something? If so, am I able to have Comcast notify of these maintenance periods in advance and let me ask to have them rescheduled to a more convenient time?

Sorry for the late response. Where would I find the log entries? I have an SMC3DG cable modem, and I can't find anything related to logs in the admin menu. Included below are the downstream/upstream signal stats.

yeah, the "US" light continuing to blink means that the modem isn't receiving a signal well enough to start connecting. This generally indicates some line quality issues at your home/business, or on the poles around it. Or, it could indicate a failing modem. It could potentially be because of some scheduled maintenance, though probably not if this keeps happening regularly.
Could you possibly post your modem signals and log entries? You can find those generally at http://10.1.10.1, http://192.168.100.1, or http://10.0.0.1. They may help us track down the cause.
