This thread is "Microsoft's Cloud Goes Dark Across the Globe". Doesn't really matter to me if it was because of a hack, an expired security signature, or little green martians. The "cloud" is vulnerable to failure. Just like a stove, refrigerator, car, computer or toilet can fail. Each of us has a responsibility to make sure we have a Plan B or even a Plan C, Plan D, or Plan E in place for these failures.
As far as anti-virus program bashing is concerned, I'm against it. If someone wants to use MSE, or AVG, or McAfee, or Norton, or "Billy Bob's Real-Time Real Deal Secuity Suite", that's their choice. If they're happy with it, so be it.
