As a result of yesterday's DDoS attack on Tucows, the Managed DNS service is down. This service is still the target of an ongoing attack. We will update this post when we have more information.

UPDATED 9:40 AM ET: Steps have been taken to change the network configuration for Managed DNS. We are currently seeing this service working normally. We will have another update at 11:30 AM ET.

UPDATED 2:45 PM ET: This problem was the result of a domain hosted by the Managed DNS service being the target of a DDoS attack. This domain has been removed from the service and the IP address of the Managed DNS servers changed. Managed DNS continues to function normally.
