A large segment of custom domain blogs experienced an outage earlier this afternoon with roughly 3.5 hours of intermittent availability.

The interruption stemmed from an issue in the way this blog traffic gets load balanced (distributed across our servers). This system has been undergoing a delicate but comprehensive overhaul to handle the tremendous amount of new traffic we’re projecting this year. This is one of many areas where our engineering team (now 22 strong) is constantly striving to make our infrastructure as resilient as possible.

It goes without saying that the performance of your blogs is our highest priority.

We’re deeply sorry for today’s failure.
