Friend of a friend said that they have had ongoing issues with ABB. Intermittent outages (especially in the evenings) for hours at a time. Call customer service and wait on hold for up to 2 hours with no answer. When they do answer the phone, they always blame the equipment (they have their own modem and router) yet, after the outage, the system will work fine for a few weeks until the next outage. Apparently, that is a common occurance around here according to social media. Lots of complaints.
