Google's Blogger aces uptime test; Tumblr stumbles

Survey by Pingdom chronicles availability performance of five blogging services

Uptime monitoring service Pingdom trained an eye on five popular blogging services once a minute for two months and all but one - Tumblr - came away with at least a passing grade.

Google's Blogger actually aced the test, being the only one of the five to experience no downtown whatsoever from Oct. 15 to Dec. 15. (Which isn't to say Blogger is immune to problems, of course, witness this significant outage from June.) and TypePad were almost as impressive as Blogger, and Posterous did well enough despite results that were described as "a bit mixed."

You can see the details, including methodology, in this Pingdom blog post.

As for Tumblr, which claims to host more than 11 million blogs, its availability troubles have been a sore spot for some time now. Pingdom says:  

Tumblr has had a rough time with their stability lately, which is made abundantly clear by this survey. Most of the monitored blogs had very little downtime, but the Tumblr blogs all had a huge amount of downtime for such a short period of time. Some Tumblr blogs were down for a total of more than two days during the two-month period of this survey. Tumblr also had the single longest outage by far, where its blogs were unavailable for almost 24 hours on December 5-6.

Here's how Tumblr reacted to that day-long stumblr:

While you might feel like you've gotten used to seeing errors on Tumblr recently, know that this is absolutely unacceptable to our team, and unacceptable for a platform determined to be the best place in the world for your creative expression.

And here's what the company has cooking in terms of remedies, according to a blog post from Friday headlined "Getting ready for 2011":

There's never 100% optimism when we feel like we've let you down. We want you to know that we're still right in the thick of the most comprehensive re-architecting our infrastructure has ever been through, and while you might still hit some bugs or errors this month, our incredibly capable team is working 24/7 to keep your blogs fast and stable. We have a solid roadmap to get Tumblr well ahead of capacity, and we're working fast to get there.

Two notable things we're right in the middle of:

  • We've dramatically expanded our engineering team, with five brilliant engineers coming on board just this month and more starting shortly. We just moved into a new office to make room for everyone. If scaling one of the fastest growing platforms in the world is up your alley, we'd love to talk!
  • After the holidays, we'll be opening our second datacenter to nearly triple capacity and prep for much faster growth next year. Today, we already light up more than a rack of new servers every week.

Tumblr is headquartered in New York City. Here's the company's jobs page for those of you in the right alley.
