Article 34 Interoperability for the purposes of in-parallel use of data processing services

The requirements laid down in Article 23, Article 24, Article 25(2), points (a)(ii), (a)(iv), (e) and (f) and Article 30(2) to (5) shall also apply mutatis mutandis to providers of data processing services to facilitate interoperability for the purposes of in-parallel use of data processing services.

Where a data processing service is being used in parallel with another data processing service, the providers of data processing services may impose data egress charges, but only for the purpose of passing on egress costs incurred, without exceeding such costs.
