It looks like we were spot-on with our estimate of ten times the normal traffic today. Our preparations held and Twitter stayed up. Only one unexpected disruption occurred and that was a network problem in our data center which caused a few minutes of service disruption some time after Steve Jobs’ keynote. With that single disruption, our uptime during the event was 97.3%
Initially, we turned off some features to shed load as we announced yesterday but we were able to turn them back on during the keynote as Twitter handled the dramatic amount of traffic. About 4% of requests during this time did return the page that asks folks to wait a few minutes and try again. However, we learned a lot during this stress test and that will translate to better performance down the line.
