Amazon resources are controlled (from a consumer viewpoint) by API - that 
API is also used by amazon's internal toolkits that support ELB (and 
RDS..).   Those (http accessed) API interfaces were unavailable for a good 
portion of the outages.

I know nothing of the netflix side of it - but that's what -we- saw. (and 
that caused all us-east RDS instances in every AZ to appear offline..)
