The termination of the whole of the online intermediation services and the related deletion of data provided for the use of, or generated through, the provision of online intermediation services represent a loss of essential information which could have a significant impact on business users and could also impair their ability to properly exercise other rights granted to them by this Regulation. Therefore, the provider of online intermediation services should provide the business user concerned with a statement of reasons on a durable medium, at least 30 days before the termination of the provision of the whole of its online intermediation services enters into effect. However, in cases where a legal or regulatory obligation requires a provider of online intermediation services to terminate the provision of the whole of its online intermediation services to a given business user, this notice period should not apply. Equally, the notice period of 30 days should not apply where a provider of online intermediation services invokes rights of termination under national law in compliance with Union law which allow immediate termination where, taking into account all the circumstances of the specific case and weighing the interests of both parties, it cannot reasonably be expected to continue the contractual relationship until the agreed end or until the expiry of a notice period. Finally, the notice period of 30 days should not apply where a provider of online intermediation services can demonstrate a repeated infringement of terms and conditions. The various exceptions to the 30-day notice period can in particular arise in connection with illicit or inappropriate content, the safety of a good or service, counterfeiting, fraud, malware, spam, data breaches, other cybersecurity risks or suitability of the good or service to minors. In order to ensure proportionality, providers of online intermediation services should, where reasonable and technically feasible, delist only individual goods or services of a business user. Termination of the whole of the online intermediation services constitutes the most severe measure.
