I never lost XFinity internet or cable during Beryl at my EaDo house.
My business (near Willowbrook) has Comcast and Logix links - Logix was down for a week, Comcast never went down
We deployed Verizon hotspots to my critical employees - access was spotty at best the first couple of days
One of my developers has AT&T fiber near the Woodlands - he was down for 3 days after he got his power back.
