Healthcare DNS changes: prepare a change record

Illustrative situation

A website migration requires DNS changes, but the team has not recorded the existing values or identified which records support email and other services.

The decision

Prepare a scoped DNS change with the current state, intended state, dependencies and rollback route. Have an appropriately skilled owner review the plan.

Rehearse this before accepting the change

Walk through a fictional failed migration using the recorded prior values and confirm the team knows which records to restore and who can do so.

Use fictional examples and an authorised test environment. Record what happened, the evidence you inspected and any issue that still needs a responsible owner.

Choose a useful measure

Track DNS changes completed with a reviewed record and successful post-change verification.

Agree the definition and baseline with the team doing the work. Review the result over a comparable period and note other changes that could affect it.

Your planning worksheet

Use these checks to prepare a discussion with your team or supplier. Tick a check when you have recorded the decision or evidence, rather than when a feature has simply been promised.
