We Made It!

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.

I was very much impressed with the way twitter handled the keynote. Only at the end the service was disrupted, but a few minutes was totally acceptable.

Great job, guys!

Well done guys - you did it. Now just charge us to keep Twitter ad free and super reliable at all times. I asked and 50% of Tweeters would pay $24/£12 a year to do so - see the poll here

I noticed it was a bit slower than normal, but hey that could just have been my POS DSL connection from AT&T.

Twitter rokth. You managed to keep your core services running in the face of a gigantic onslaught of traffic. Well done. Now maybe TechCrunch will get off your case for a while.

Awesome job, Biz + Twitter team! I thought for sure the WWDC mascot would have been the failwhale, but you guys definitely delivered. Congrats!

Of course, now you're on the hook for keeping uptime. "If you can survive WWDC, you should be able to survive anything!"

Hey guys. Great work. That was really impressive. I'm glad to see you guys made it through and learned a little along the way. A stress test like that can only mean better things for the future of Twitter. Has TechCrunch eaten its words yet?

You're kidding right? 97.3% isn't something anyone should be proud of. And letting the production systems become your test bed for stress testing? Are you serious? Turning off features only masks the underlying problems.

Still lots of work to do....
