Hosted DNS Performance Issue
Incident
Report for Linode
Resolved
At this time we have re-enabled AXFR on our DNS service, and this issue has been fully resolved.
Monitoring
Since the attacks on our name server infrastructure have not stopped, we are expecting to have to leave AXFR functionality disabled for the foreseeable future. We recommend customers who depend on this feature to explore short-term alternatives.
Update
Our engineers are continuing to harden our DNS systems from the ongoing attacks. We will provide an update once additional progress has been made.
Identified
The denial of service attacks against our DNS infrastructure have resumed at this time.
Update
There have been no additional DNS attacks detected throughout the night. Our DNS systems remain operational with AXFR disabled. We will continue to closely monitor the situation.
Update
Our staff is continuing to monitor for further attacks. At this time our DNS systems are continuing to function normally, AXFR remains disabled.
Update
Our engineers have taken steps to further harden our DNS systems against further attacks. It should be noted, however, that AXFR functionality has been disabled for the moment due to these measures. We will resolve this once we are able to implement additional levels of mitigation. We are continuing to monitor for any further disruptions. Thank you for your patience.
