Internet Outage After Scheduled Maintenance

Yesterday, there was a scheduled maintenance event at my location at around 11:00am.  I received noticed that we could expect service interruption.  At around that time, my internet went out.  Soon afterwards, I received a notice that the work was completed and everything is up.  I waited but my internet was still down.  I went down to my basement to reboot the modem and router.  Still no service.  I waited and waited.  I checked my Xfinity App and it said that there was no service issue in my area.  Late last night, I swapped out my current modem with my previous one and tried to activate it and still nothing.  I thought maybe by coincidence my modem went bad at the exact time that I had scheduled maintenance.  I then swapped my current modem back in.  I looked at my Xfinity App and saw that there is another scheduled maintenance event at 3:30am tomorrow (2/27/26). 

This morning, I hooked up my laptop directly to the modem to take a look at the logs and signal quality.  It doesn't even show any signal quality metrics.  I looked at the log, and I see many messages about timeouts and "No Ranging Response Received". 

About 5 years ago, I had a technician over because I constantly had bad signal quality on my modem with lots of dropouts since I moved into my house.  I lived with bad signal quality for over 15 years.   The technician measured the signal quality and immediately went out to the local distribution point and said that they needed to do some repairs there.  Since then, my signal quality has been excellent and for the past 5 years, service has been rock solid.  I haven't experienced any issues leading up to yesterday.   I just find it weird that things suddenly went bad right after yesterday's scheduled maintenance.

I really don't think there is anything wrong inside my house.  My internal connections are good.  I don't think there is anything wrong with my modem or router.  I think the problem is with the line or distribution point outside of my house.  Since they are scheduled to perform service maintenance in my area tomorrow, would it be possible to have them check the lines to my house?  I will be headed to my office today (I normally work at home) because of my internet issues.
