I wonder if the next thing will be an email from Google saying "if you don't want us to turn off your Google again, send us $(calculated-amount-you-will-probably-pay). That $ value is pretty high, far higher than their current revenue from me (adblocking...).
I don't think it was storm related. Google routinely takes down entire datacenters without affecting user visible services. It's some config or software error which either got fixed or rolled back really quickly.
