Recital 30

The very rapidly changing and complex technological nature of core platform services requires a regular review of the status of gatekeepers, including those that it is foreseen will enjoy an entrenched and durable position in their operations in the near future. To provide all of the market participants, including the gatekeepers, with the required certainty as to the applicable legal obligations, a time limit for such regular reviews is necessary. It is also important to conduct such reviews on a regular basis and at least every 3 years. Furthermore, it is important to clarify that not every change in the facts on the basis of which an undertaking providing core platform services was designated as a gatekeeper should require amendment of the designation decision. Amendment will only be necessary if the change in the facts also leads to a change in the assessment. Whether or not that is the case should be based on a case-by-case assessment of the facts and circumstances.
