On April 8th 2026, Liongard will be deploying a fix for a known issue affecting the Internet Domain/DNS Inspector. As part of this deployment, you may experience a one-time false positive alert. This article explains what to expect, why it's happening, and what (if anything) you need to do.
What's Happening
A bug was identified in the Internet Domain/DNS Inspector where sub-domain changes trigger inaccurate actionable alerts. Specifically, the inspector incorrectly reports a sub-domain as being continuously added and then removed, causing repeated false positive alerts to fire for affected environments.
What to Expect During Deployment
When the fix is deployed, you may see a single false-positive alert generate for environments where the Internet Domain/DNS Inspector is active and an alert rule is configured. This is expected and is a direct result of the fix being applied — it is not indicative of an actual change in your environment.
This alert will not repeat after the deployment is complete.
Do I Need to Do Anything?
No action is required. You can safely dismiss any alert that fires on or around April 8th related to Internet Domain/DNS sub-domain changes.
If you have alert notifications configured (email, PSA, etc.), you may want to give your team a heads-up that a one-time alert is expected, so it is not mistaken for a real issue.
What If Alerts Continue After April 8th?
If you continue to see repeated false-positive Internet Domain/DNS sub-domain alerts after April 8th, please contact Liongard Support so we can investigate further.
