This is good news, especially if you're power happens to go out or anything, as Comcast will offer FREE WiFi today in Philly, even if you're not a customer!
"If you’re in need of a hotspot, Comcast advises users to select “xfinitywifi” among the network options from your computer’s WiFi menu.
From there, open a new browser. XFINITY customers can sign into their accounts, and non-customers can log-in through the “Not an XFINITY Subscriber” option. You’ll be able to stay connected through Sunday, March 11, when (hopefully) the storm will have safely passed and everyone’s power will be restored.
Non-customers will have to refresh their free WiFi sessions every two hours."
