Artikel 34 Interoperabilität zu Zwecken der parallelen Nutzung von Datenverarbeitungsdiensten

Article 34 extends the switching and interoperability obligations already established in earlier articles of this regulation — specifically those covering switching processes, contracts, and interoperability standards — to also cover scenarios where a customer uses multiple data processing services simultaneously, rather than switching from one to another.

It is a relatively brief article that acts as a bridge, ensuring that the protections built around switching are not bypassed simply because a customer chooses to run services in parallel.

It also addresses the cost dimension of parallel use, setting a clear limit on what providers can charge for data egress in that context.

Important points:

• Providers of data processing services must comply with the key switching and interoperability obligations from Articles 23, 24, 25, and 30 even when customers are using their services in parallel with another provider, not just when switching.
• Data egress charges in a parallel-use scenario are permitted, but providers of data processing services may only charge up to the actual egress costs incurred — no margin or additional fees are allowed.
• This article does not create standalone obligations but applies existing ones to the parallel-use context, meaning compliance with those earlier articles is the foundation for compliance here.
