I recently went through several rounds of interviews with Twitter. I had submitted my resume blindly via their website, rather than having any internal contacts there. At first, I didn't even consider working at twitter, both thinking I didn't want to work there and having not thought that it was a company I would be interested in, in any form. After interviewing though, I realized I really wanted to work there... sadly though - I didn't get the job. I wanted to work there because they are really constrained with their staff relative to the size of infrastructure issues and projects they have. Though, there was one interesting comment made by the hiring manager that may shed light on some of these outages: he said "We have a lot of young, very bright guys here - but they don't have a whole lot of experience" Meaning that they are in their early/mid twenties - so its not like they have years of experience building really large infrastructure. I just wonder how robust twitters architecture is with this in mind. They have, fairly recently, drawn people in from Yahoo and Google's networking teams - so that's really encouraging, but I wonder if there were any architectural choices that were made earlier that might need some major overhaul to provide the resiliency they need. Further, as they scale out their infrastructure by expanding their datacenter footprint in California, and ultimately bring up other sites, I am sure they will stabilize greatly.
