Xfinity/Comcast customers lost internet, phone, and TV service Monday morning around 10 am. And an initial promise of service restoration by 1 pm has now been updated to 8 pm.

It appears that thousands of Xfinity customers across the middle of San Francisco, including Polk Gulch, Pacific Heights, Japantown, the Upper Haight, Castro, and Glen Park neighborhoods, are without internet service today, due to reported "network damage" that Comcast says it is working to fix.

The incomplete map below indicates where outages are occurring, with the full purple ovals indicated more than 2,000 customers in that area without service.

KRON4 picked up on the problem, and while Xfinity internet outages are not exactly rare, they typically do not go on for entire days.

Xfinity, per usual, "apologize[s] for the inconvenience," and the exact reason for the outage has not been given.

This is a developing story.
