When is Carfax mileage reported/updated?

I recently replaced my cluster and I don't really ever plan on selling my car and I would rather not deal with carfax thinking I rolled my odomoter back.

Is it reported/updated every time you take a vehicle in to any vehicle repair shop? Even lube shops?

It's recorded during provincial inspections. At least that should be the only time.
