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.
How we deliver in Greece
We deliver enterprise connectivity across Athens and Thessaloniki via OTE, Nova, and Colt. Greece sits naturally alongside \[Italy\](/countries/italy) and \[Cyprus\](/countries/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.
Carriers, infrastructure and routing
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.
