Considering that Public just blasted out a text about free data and a holiday contest at 12:25 (ish) today, there are probably a T O N of people trying to sign in and the servers just can't handle the amount.
My favorite thing about the holiday season is a dead split between a)paying a reasonable rate for phone service, and b) the VEGAN NOG!!! No matter how or why you're celebrating - Happy holidays everyone!
