We're seeing DNS resolution errors for .io domains (including our www.flyingcircus.io
and my.flyingcircus.io) that appear to be caused by an issue in the global DNS infrastructure. Pingdom has also acknowledged that a large number of customers are reporting suspicious DNS resolution errors. Our DNS servers are working fine and your services are not affected by this directly. Resolution of our domains within our data centers is not affected. Recursive resolution for third party domains is likely to be affected by this as well.
