Business Internet & Enterprise Connectivity in Greece

Athens is mid-transformation. Digital Realty delivered ATH3 — the largest data centre in Greece — in August 2025. Microsoft is investing €900 million in three hyperscale facilities in Eastern Attica to establish an Azure Region in Greece. Data4 is building a multi-phase campus with €300M+ committed. Google's Blue-Raman cable passes through Greece. Meta's 2Africa cable (45,000km) launched in Q1 2025 with Vodafone capacity. The country's ICT market is growing at 12.5% CAGR through 2033. This is no longer a peripheral EU market — it's becoming a Southeastern European digital gateway.

The Connectivity Landscape

OTE (Cosmote) is Greece's largest carrier — investing heavily in FTTH to cover 2.5+ million homes and businesses by end 2025, with 85%+ 5G population coverage targeted. Nova (formed from the 2023 merger of Wind Hellas and Vodafone Greece) is the second-largest operator, with 95% 5G coverage and 540,000 FTTH-connected premises by end 2024.

We work with OTE, Nova, and Colt across Greece. For enterprise delivery in Athens and Thessaloniki, Colt is our primary recommendation where on-net. The carrier landscape in Athens has reached 40+ unique carriers as of September 2025, making it a genuine enterprise connectivity hub with competitive pricing in colocation-adjacent environments.

Greece's submarine cable position is strengthening: Google's Blue-Raman connects France, Italy, Greece, Israel, Jordan, Saudi Arabia, Djibouti, Oman, and India — making Greece a routing waypoint between Europe and Asia. 2Africa (Meta) brings 45,000km of capacity through the Mediterranean. Thetis Express — a new cable connecting Crete to the mainland at 180Tbps — connects into the 2Africa system. The Magna Grecia Cable (Italy-Greece, 323km) is in feasibility study, due July 2025.

What We Deliver in Greece

We start with your requirement, not a carrier list. Single circuit or dual? What resilience model? Is carrier diversity a requirement? What's your lead time? Once we understand that, we'll recommend the right options for your specific address in Athens or Thessaloniki. Our Nexus platform covers 2.5 billion buildings globally — we know what's serviceable before we make a recommendation. Greece sits naturally alongside Italy and Cyprus in regional programmes covering Southern Europe and the Eastern Mediterranean. For international legal, financial services, and professional services clients with Greek operations, we manage Greek circuits within a wider European SLA framework. Lead time: 35–40 working days in Athens.

Frequently Asked Questions

Which carriers do you use in Greece?
We don't work from a fixed panel. We qualify your requirement first — resilience model, carrier diversity, lead time, vendor preferences — then recommend the right carriers for your specific address. OTE, Nova and Colt are among the options in Greece, but carrier selection is driven by your requirement and location.

What is the Microsoft investment in Greece?
Microsoft is investing €900M in three hyperscale data centres in Eastern Attica (Spata, Paiania, Koropi) to establish a Microsoft Azure Region in Greece. This will create direct Azure cloud on-ramps in the country.

How long does delivery take?
35–40 working days for enterprise circuits in Athens. Regional cities take longer.

Is Greece relevant for Middle East connectivity routing?
Yes — Google's Blue-Raman cable transits Greece en route from Europe to the Middle East and India. For enterprises with requirements spanning Greece, Cyprus, and the broader Eastern Mediterranean, Greece's cable position is relevant to routing design.
