Great overview. If I sold on Etsy, I would be more confident that they are proactively striving to reach 100% uptime and quickly addressing actual downtime.<p>I love the structure of their problem solving references: root cause analysis, time line of event post mortem, single point of failure. And, of course, the fact that they actively measure the real customer experience from multiple places around the world. Customers may not realize it's a local infrastructure problem when they go to Etsy so being able to proactively find and address these issues makes for fewer customer support calls and more satisfied customers.<p>Kudos to Etsy for the post.
