I find it very surprising that this is not the top post at the moment. My partner went to work at her bar at 5PM ET, and their Square services which processes reservations, transactions, payroll and even staff scheduling is at a stand-still. It seems like this is the case for a huge amount of bars, restaurants, and whatever other line-of-business Square seems to have infiltrated itself into to cause one massive single point of failure.
I feel for the engineers at this point in time, but their status page being updated at a 45 minute cadence with very little in terms of resolution is.. not so good.
