One Source Networks (OSN), a managed communications solutions provider to large, global enterprises, extends its presence in Europe with flexible data centre infrastructure from Epsilon

OSN delivers unified communications and managed Cloud networking services to Fortune 1000 enterprises. The company’s customers span verticals, from healthcare and insurance to technology and energy.

To deliver its industry-leading communications services simply and cost-effectively, OSN requires partnerships that provide reliability and scalability. Epsilon has over a decade of experience in delivering outsourced services globally, which means that OSN can trust it to deliver consistent, high-quality solutions in one of the world’s busiest communications hubs.

Epsilon’s carrier-neutral data centre facility in London, UK was an ideal fit for OSN, giving the company a foundation to serve the international requirements of its enterprise customers.



OSN needed to extend its presence in Europe with a partner who had data centre infrastructure that could scale with its growing requirements.


Seeking the support of a long-term partner who understands the requirements of delivering high-performance applications and communications services, OSN turned to Epsilon for its data centre infrastructure needs in London.

Epsilon has not only provided racks in its data centre facility but also opened up opportunities for OSN to leverage its infrastructure and interconnect with customers, partners and service providers. From this hub, OSN can also access Epsilon’s over 600 carrier relationships. The company has been able to grow its presence in Epsilon’s facility over the past year.

Epsilon also operates data centre facilities in Singapore and Hong Kong where it is able to support OSN and its customers doing business in these regions. Epsilon’s data centres offer more than just state-of-the-art carrier-neutral colocation spaces, they deliver other benefits and services designed for operators that require a managed presence as well as robust local connectivity to other major data centre facilities.

Epsilon delivered data centre solutions that we can trust. It is important for us to have a long-term partner who is as deeply focused on high quality service delivery and customer support as we are. Epsilon has impressed us with their commitment to getting it right and being prepared to serve not just our needs today, but also those we may have in the future.
