Upstream registration failure after area maintenance — two units same building

After the storm outage, my modem locks downstream but won't complete upstream registration — upstream light flashing, never goes solid, never comes online. The app posted 2 AM area maintenance which now shows complete, but the modem still won't register. A second unit in my same building, on a different modem, has the identical failure at the same time. This looks like an upstream plant fault on shared wiring, not household equipment. Requesting a network/line maintenance escalation rather than a premise tech.

Concern moved here to the Customer Service help section for greater exposure to Comcast corporate employees (The Digital Care Team) for assistance.

I completely understand the importance of having your services running smoothly and will do all I can to begin the process of correction. To begin, would you mind sending me your name and the address to your account in a Direct message?

Here's how to send a direct message (private message);


Click "Sign In" if necessary.
 
Click the "Direct Message" icon  in the upper right corner. 

Click the "New message" (pencil and paper) icon.
 
The "To:" line prompts you to "Type the name of a person". Instead, type "Xfinity Support" there.
 
As you are typing a drop-down list appears. Select "Xfinity Support" from that list.
 
An "Xfinity Support" graphic replaces the "To:" line.
 
Type your message in the text area near the bottom of the window.
 
Press the "Enter" key on your keyboard to send it.
