It’s not news to anyone any more, so I’m sure everyone knows Amazon Web Services (our major cloud infrastructure provider) suffered an outage within one of their availability zones on Sunday June 5th. AWS is split up into various geographic regions, and within each region, a number of availability zones. I’m going to assume most readers know about this, but if you don’t, check out Amazon on how they describe these things. On Sunday one of these availability zones suffered a “power event”, owing to Sydney’s wild weather on the weekend, bringing it to its knees. Lots of Australian based websites had major problems.
