Post-mortem for DNS outage on July 23rd

From approximately 09:35 UTC until 10:00 UTC, July 23rd 2012, DNSimple experienced an outage across four name servers. This outage appears to be the result of a distributed denial of service (DDoS) attack. Due to the attack we were unable to respond to DNS requests in a timely fashion. Our job processing queue simultaneously stopped due to a failed deployment. The backup in the job queues resulted in new subscriptions timing out and impacted customers updating DNS records.
