pg, or someone else from HN... Could you please edit this title for accuracy? Maybe, "Poorly designed sites taken out because of problems in one Amazon availability zone."
For many sites, a single server in a single zone (e.g., a non redundant server, an instance, a slice, a VM, whatever) is the right decision for ROI.
For many sites, the money spent on redundancy could be better spent on, say, Google Adwords, until they're big enough that a couple hours downtime has irreplaceable costs higher than the added costs of redundancy (dev, hosting, admin) for a year.
Yes, it is editorializing. My point is, but I guess too subtle, that the current link text is very much an editorial comment, especially since the content at that link location has nothing to do with the sites mentioned in the link text.
This issue is affecting both an EC2 Zone and Amazon's RDS servers, which are technically multi-zone. There are a ton of well-architected apps and sites that have been affected. Unconstructive...
