Confusing email from Xfinity

I am reproducing a portion of an email I received from Comcast today (April 24, 2025):

"...in the coming days, we'll be making improvements to the Xfinity network in your neighborhood. ...
"Our most current information has us starting work in your area on 01/21, affecting service at [address deleted]. 
"How this work will affect you
"As our teams work to make these enhancements, you can expect service outages. This downtime will affect all of your Xfinity services, and if you are an Xfinity Voice customer, you will not be able to call 911 from your wired phone line."

I tried the automated assistant to see what that January date should have been, but that was hopeless. I then called Comcast, and the agent told me she couldn't see that any work had been scheduled for my area.

Now, an outage affecting my telephone service is significant, and I want to know what's going on. If no work is scheduled, what triggered that email? And if work is scheduled, how can I find out when--and how can I trust any email from Comcast warning me about it (or anything else, for that matter).
