I’m not sure what happened with our bandwidth usage this month but it was way up from any previous month and we just used our one “free" excess usage month from Xfinity. This would have cost $60 extra this month. I will have to keep an eye on usage and consider adding unlimited data for $30 a month. We didn’t make any notable changes in devices or usage so I’m not sure what drove the jump.
