FYI Netflix is down

Sat Jun 30 20:08:40 UTC 2012

If I recall correctly, availability zone (AZ) mappings are specific to
an AWS account, and in fact there is no way to know if you are running
in the same AZ as another AWS account:

http://aws.amazon.com/ec2/faqs/#How_can_I_make_sure_that_I_am_in_the_same_Availability_Zone_as_another_developer

Also, AWS Elastic Load Balancer (and/or CloudWatch) should be able to
detect that some instances are not reachable, and thus can start new
instances and remap DNS entries automatically:
http://aws.amazon.com/elasticloadbalancing/

This time only 1 AZ is affected by the power outage, so sites with
fault tolerance built into their AWS infrastructure should be able to
handle the issues relatively easily.
