Sify Network

Sify owns and operates India’s largest MPLS network,
7 data centres and offers an extensive international network

Indian Regional Network

Sify owns and manages one of the largest IP Multiprotocol Label Switching (MPLS)-enabled networks in India.
With more than 2700 MPLS points of presence (PoPs) enabling more than 100,000 active customer connections, the Sify IP network was purposely designed with high availability and business reach from its inception.
Built to a high carrier-class grade design, the Sify network encompasses six wholly-owned city fiber metro networks that are interconnected to a geographic network diverse high-capacity national backbone network.
The Sify network was built to support and provide the digital superhighways for the new digital business India. We provide digital bandwidth services to enterprises, content providers, over-the-top (OTT) providers and international network operators with speeds up to 100 Gbps throughout India.​

Geographically diverse fiber in the network encompasses dual PoPs with the latest Metro DWDM access network infrastructure. This ensures that the networks serving our customers in major cities and across major international gateways never go down.
We continue to expand the capabilities of the Sify network to handle spiraling data volumes. Our N*10G Metro access ring network with multi-service access nodes (MSANs) across major Metros ensures high-quality traffic delivery-even if one fibre route is compromised.

International Network

We offer one of the world’s most extensive international networks to connect users and customer locations across the globe. In Atlantic and Asia Pacific regions, we have diverse cable assets and multiple POPs over different geographies with direct connectivity to a range of major IP network operators.
Sify is carrier-agnostic. We’ve partnered with Colt, EU-Networks, GTT, PCCW, SingTel, Testra, CenturyLink, Telia, Verizon, Vodafone and Zayo to extend services for our customers to international locations.
The Sify network has multiple levels of redundancy including oceanic and cable―and a robust backbone of interconnecting hub locations.
We have peering points used to build redundant international network connections to the United States, Europe, the Middle East, Africa, Latin America and the Asia-Pacific region. POPs are located in New York, London, Marseilles, Los Angeles, Dubai, Singapore and Hong Kong over redundant cable systems on transatlantic and transpacific paths. This allows us to provide end-to-end connectivity to global corporations and to provision remote management services for multiple locations both within and outside of India.
