Twitter Says Stability Should Improve [blog.twitter.com]
From a site stability and service outage perspective, it's been Twitter's worst month since last October.

What's the problem?
Last Friday, we detailed on our Engineering blog that this is going to be a rocky few weeks. We're working through tweaks to our system in order to provide greater stability at a time when we're facing record traffic. We have long-term solutions that we are working towards, but in the meantime, we are making real-time adjustments so that we can grow our capacity and avoid outages during the World Cup.

As we go through this process, we have uncovered unexpected deeper issues and have even caused inadvertent downtime as a result of our attempts to make changes. Ultimately, the changes that we are making now will make Twitter much more reliable in the future. However, we certainly are not happy about the disruptions that we have faced and even caused this week and understand how they negatively impact our users.

I think it's awesome that T is using and making contributions to Cassandra, Thrift, Scribe, Pig, Hadoop... all open source.

Their challenges are similar to but different from huge data gatherers like Facebook, Google, Yahoo, all of whom have massive Hadoop installations. They are also willing to share their mistakes and solutions with the world. That's a policy & culture I can appreciate.

If they'd just ban everyone trending Justin Bieber the problem would be solved.

I built and automated a twitter account for my website. Suprisingly it generates some traffic but many I don't get the appeal. I created some lists where I follow people relevant to my interests but it's still just so much noise. I don't get how they continue to grow in popularity.

No Twitter, I don't think you really understand how negatively it impacts your users. If you did, you wouldn't allow this to happen for 7+ days. Twitter was up and down for a whole week. It started at about the same time every day too. I was starting to think that Twitter were under an attack of some sort, I still think that was the case and not some scalability thing.

Note for Twitter: Maybe if you'd pay attention to the Report for Spam queue and all the crap bots running loose on the platform, you'd have some more bandwidth for those folks that it is negatively impacting. You're all about the numbers and I've seen spam accounts live on for over a year now. The Report for Spam function is a placebo link.

I don't go there half as much now because I'm fed up to the back teeth of looking at that picture of the damn whale. Continual outages say to me: "we don't really care enough to fix it."

poor show IMHO.

If you're this upset about a website like Twitter being down, I think the problem isn't with the website downtime....

Anytime Twitter is down it is positively affecting everyone.

It's been worse than ever lately,

I think we should add "Twitter stability" to the list of oxymorons like "Wordpress security" and my favorite "Unlimited Data" capped at 5GB.

And remember, Twitter is the poster child of the "cloud based" website era. The entire backend of Twitter is serviced by Amazon cloud services.

Hmmm, I thought the cloud was supposed to make sites rapidly scalable and eliminate downtime due to traffic surges. It would behoove Amazon to help Twitter sort this out before potential customers start questioning the platform.

In twitter's case it's "rapidly whale failable"

Bet you can't tell I'm annoyed with Twitter today.

We’re seeing periodic high rates of errors on Twitter.com.


Ah-ha! I got on early this morning in anticipation of Cloud Precipitation.

No, no, no the sky is not falling. The Fail Whale is rising! On the plus side, I might actually be able to get some work done today ;)

I think they lied. The Fail Whale mating season has been in full swing for the past two weeks. Getting Fail Whales consistently now every day, particularly during prime time. They can't handle the load. You would think with all the funding they've received, they would have been proactive in their approach to bandwidth and not reactive like they are doing now.

Twitter is the Poster Child for why Cloud Computing sucks.

I put my account into Protected Mode and am taking a hiatus. Maybe even an extended one. I need to get away from that time suck anyway.

Twitter is over capacity.

^ Maybe that can be worked into a new tagline for Twitter.

I quit Twitter on 2010-06-29. It looks like I got out just in time too, everyone is complaining about the Whale!

2010-07-02 Investigating Elevated Error Rates 59 minutes ago

We’ve received reports of elevated error rates for users; we’re currently investigating.

Update (9:47 AM PST, 16:47 UTC): This is unplanned downtime. Infrastructure and operations engineers are working to fully restore Twitter. Expect more updates soon.

Update (9:55 AM PST, 16:55 UTC): We are now recovering from a period of high unavailability.


I'm guessing they have some folks over there who don't know what they're doing. They've had Fail Whale challenges now every day beginning the first part of June 2010. It is ongoing as of this moment. I think they're running Windows Servers out of their basement or something.

Screw you Twitter!
