How to handle unexpected DNS changes
Identify what changed, when it changed, who may have changed it, and what the operational impact is.
The situation
DNS records can change for many reasons — platform migrations, manual edits, provider changes, or unauthorized modifications. When a change happens unexpectedly, the priority is to understand what changed, assess the impact, and decide whether to remediate or accept it.
Before you begin
For agencies: Before taking action on an unexpected DNS change, confirm with the client whether the change was intentional. A platform migration or new service could explain changes that appear suspicious.
The operational path
The goal isn't just to find the error. The goal is to move from detection to a verified infrastructure state.
What could have caused this?
Cause
What changed
Possible impact
Platform migration
Client moved to a new provider or service
DNS records updated, may break existing configuration
Manual edit
Someone edited DNS directly without coordinating
Uncoordinated change — may or may not be correct
Provider change
Nameservers or registrar changed
All DNS records potentially affected
Automated tooling
Deployment pipeline modified DNS
Change may be expected but undocumented
Unauthorized change
Change made without proper authorization
Security risk — requires immediate investigation
Step by step
Infraova logs every DNS change it detects, including the previous value and the new value. Start here.
What to check
Expected result: You know exactly what changed and when Infraova detected it.
With Infraova
Infraova's DNS change timeline shows every detected change with the before and after record values.
Determine what the change affects. Not all DNS changes are equally consequential.
What to check
Before reverting anything, confirm whether the change was expected.
What to check
If the change was unauthorized or incorrect, propose a revert. If intentional, document it.
What to check
You decide. Infraova executes.
Infraova can propose and execute an approved infrastructure change, but it does not independently decide to modify client infrastructure. Every proposed change requires explicit authorization before execution.
Key takeaway
Unexpected DNS changes require investigation before action. Understand what changed, confirm whether it was intentional, and then decide — revert or accept. Never revert without confirmation.
