Rimm is a sinking ship

So a work colleague shared an interesting article about the recent Blackberry Outage. From what I understand they placed a Cisco router instead of a switch. I know that Cisco switches are complicated devices however when you are running a multi-billion dollar company, you must have backup plans, or devices in place in case such a thing happens. I work with medium sized businesses that range from 100-500 employees, which clearly don’t have as much money to spend on IT as Rimm does. Yet their IT infrastructures are usually built to withstand multiple points of failure, so how does one switch failing take down a corporation like Rimm? I really have trouble believing that Rimm will continue to sail along. Maybe Apple will buy them out for their patents.
