RETN launches Flex IX: the industry’s first Zero-waste IX and Transit

London – October 20, 2025 – RETN, the leading independent global network services provider, today announces the launch of Flex IX, a new wholesale connectivity solution that, for the first time, combines Remote Internet Exchange (IX) access and IP Transit in a single service.

RETN analysis shows that at least 70% of capacity at industry peering and interconnect points goes unused – highlighting a long-standing inefficiency: IX bandwidth often sits idle when peers are inactive. Flex IX solves this by combining Remote IX and IP Transit on a single port, automatically converting unused peering bandwidth into IP Transit with the option to burst beyond the committed rate – allowing operators to fully utilise purchased capacity without the cost and complexity of separate services.

“This is a first in our industry,” said Tony O’Sullivan, CEO of RETN. “Flex IX ends wasted capacity. Carriers, ISPs and Content networks can commit once and be certain that their bandwidth is always working for them – whether for peering or transit. It simplifies operations, increases efficiency, and builds resilience into networks.”

Key benefits of Flex IX include:

• Zero waste – unused IX capacity automatically becomes available for IP Transit.
• Resilience by design – if a peering partner or IX has an outage, traffic continues over transit (based on BGP setup).
• One solution – peering and transit combined on a single RETN port and CDR.
• Global reach – access to RETN’s Remote IX portfolio, including: AMS-IX (Amsterdam), BBIX (Tokyo, Hong Kong, Singapore), BCIX (Berlin), BIX (Budapest), DE-CIX (Frankfurt), DTEL-IX (Kyiv), ESpanix (Madrid), France-IX (Paris), INEX (Dublin), JPNAP (Tokyo), JPIX (Tokyo), LINX (London), MIX (Milan), Netnod (Stockholm), VIX (Vienna).

William Manzione, Product Manager at RETN, added: “We designed Flex IX because we care about the quality of our customers’ networks. Every network buyer knows the frustration: you commit to IX capacity, but traffic patterns shift, peers aren’t always active, and valuable bandwidth sits unused. Meanwhile, you’re managing separate contracts for IX and transit, adding cost and complexity. Flex IX is designed to address this.”
