Does anyone know if this really is just one AZ? Seems like an awful lot of larger sites are down. I'd expect at least some of them to be multi-AZ by now.

I'm multi-az and am being impacted. I also use multi-az RDS adn its being impacted. So calling BS on the 1 az impact.

This would be a great time to post a guide to architecting systems for failover using AWS. Anyone got a great guide?

We (Twilio) have released a number of articles & presentations in this area:

It's strategy as opposed to how-to but the principles apply.

Earlier quoted context omitted.

Amazon is downplaying the problem. It is affecting many large sites.

Many large sites which aren't properly architecting their infrastructure to deal with the commodity nature of the cloud.

If netflix is down, then it's something most companies who know how to design fail over can't cope with.
