John Adams on Fixing Twitter: Improving the Performance and Scalability of the World's Most Popular Micro-blogging Site

Twitter is suffering outages today as they fend off a Denial of Service attack, and so I thought it would be helpful to post John Adams’ exceptional Velocity session about Operations at Twitter.

Good luck today John & team… I know it’s going to be a long day!

Update: Apparently Facebook & Livejournal have had similar attacks today. Rich Miller from Data Center Knowledge reminds us that this is just the latest in a series of major attacks.
