Yes, we had a short outage this morning. We're still investigating the root cause but the symptoms were essentially a simultaneous slow down across all name servers. It's quite possible this is part of the same DDoS that Zerigo is facing, we're not certain - we've been seeing lots of spikes today from various IP addresses (but we've actually been seeing similar patterns for quite some time, as have other DNS providers).

We'll post a more extensive post-mortem once we have a better understanding of what happened, but our main goal at the moment has been to ensure systems remain stable and responsive.
