And you're in the electric power BUSINESS!

Up here in northern CA we used to joke that PG&E's company song should be the 
Simon & Garfunkel "Hello Darkness my Old Friend."

Subject: Re: Check out Massive Amazon cloud service outage disrupts sites

Our data center folks insist on dual power feeds for everything, sometimes 
infuriatingly so. To test power redundancy, they occasionally drop one power 
feed or the other--with ample heads up--and check that all devices are 
functioning. Other than call-home events, we have not had any surprises so far. 

Testing for a full power outage (both sides) is a lot harder, but it has been 
done here a few times.
