Was Coast To Coast Comcast Outage Another BETA Test Before Internet Is Taken Down?

Back on February 14th, Susan Duclos told us about a warning from internet security guru John McAfee that a massive internet outage across the country could cause a catastrophic cascade of bad news with a significant power grid failure likely along with the loss of emergency services, water and natural gas distribution, the failure of dams and nuclear power plants and quite possibly the most alarming failure of all, that of the financial system and institutions that could be devastating to the markets and the unprepared.

Is it only a coincidence that a day after Susan's warning, Comcast cable providers were hit with a massive cable and internet outage all across the country...

According to Down Detector, cities affected with this Comcast outage ranged from the East coast to the West coast and everywhere in between with the San Francisco area, Washington state and Oregon suffering outages on the West coast while extremely heavy outages were reported from the Boston area south to the Washington DC area and down into South Carolina, Georgia and Florida on the East coast.

With a recent warning going out in the International Business Times that ISIS is trying to destroy the internet via massive cyber attacks that could at least temporarily take down the internet, one of the latest stories from Mac Slavo over at SHTFPlan referenced previously tells us what the biggest danger of a prolonged internet outage would clearly be: In a "Cashless Crisis" with digital payments, civilization comes to an end until power is restored.”

As Slavo tells us.:

The coming brave new world may also be a fragile one.

As most of the Western world is pushed into abandoning cash and embracing a fully digital cashless grid, it is apparent how vulnerable populations will become in times of crisis.

If the power grid were to go down in a storm or an attack, it is readily apparent that the system of commerce would go down with it; payments would stop and desperate people would line up for help. Those with their own supplies, barter items and physical commodities will remain the most comfortable, but the very fabric of society could come unglued.
