Colt takes over Lumen’s European networks

Colt Technology Services, headquartered in London, completed its acquisition of Lumen Technologies’ European, Middle Eastern, and African (EMEA) business. Colt paid US$1.8 billion cash for the assets, which included Lumen’s entire terrestrial and subsea networks, data center and network services in the region. The deal also includes Lumen’s trans-Atlantic subsea networks, the regional employees and customers contracts.

Regarding the Internet backbone (Autonomous System 3356), this IP infrastructure will be owned regionally by a respective Colt or Lumen affiliate, but it will be co-managed by multiple entities. Rather than split the AS3356 along the physical asset ownership boundaries, Lumen and Colt are building a long-term commercial relationship to maintain and operate this IP network globally.

"We're excited about what this transaction does for our customers and for Lumen," said Kate Johnson, Lumen CEO. "Our focus on building deep relationships with strategic partners allows us to simplify our business while delivering a seamless networking experience for our multinational customers. Through our strong relationship with Colt, both companies are well positioned for future growth."

Colt: New Business Outcomes with NaaS

There are many definitions of Network as a Service (NaaS) floating around. Is really something new or just a new umbrella term for existing services?  Mirko Voltolini, VP Innovation from Colt, explains:

  • NaaS is a groundbreaking approach that allows the orchestration of services across multiple domains and providers, enabling the creation of diverse business outcomes. It combines connectivity, cloud solutions, security, and IoT from various providers to create specific solutions for industries like manufacturing.
  • APIs play a crucial role in NaaS, enabling the composition of different service components and avoiding manual stitching. Colt started building its NaaS proposition, Colt on Demand, in 2015, and has been pushing the industry to adopt the MEF LSO APIs as a common way to connect with each other.
  • The response from customers and partners has been positive, as NaaS solves the complex problem of telecom industry fragmentation. The ecosystem is growing, with more providers adopting automation and the MEF LSO APIs, and Colt believes the momentum will continue to build.

Join Mirko and Jim Carroll on a walk around MEF's Global NaaS event in Texas as they discuss the future of NaaS, the role of APIs, and how Colt is participating in this innovative field. #MEFGNE
