Business Internet & Enterprise Connectivity in Belgium
Brussels is where EU institutions, international law firms, and multinational headquarters converge — and where the connectivity requirements that follow are more complex than the country's size suggests. The Belgian data centre market is experiencing significant growth driven by AI workloads and enterprise cloud repatriation. Brussels has 36+ carriers and direct cloud on-ramps to Google Cloud and Azure. Antwerp hosts the only Tier IV certified data centre in Belgium. We work across both cities.
How we deliver in Belgium
We deliver across Belgium via Proximus, Orange Belgium, Telenet, and Colt — for enterprise DIA, Ethernet, and capacity services in Brussels and Antwerp. For multinational clients managing circuits across \[France\](/countries/france), \[Netherlands\](/countries/netherlands), and \[Germany\](/countries/germany) alongside Belgium, we run the full estate under a single commercial relationship and SLA framework.
Brussels's proximity to EU governance and financial regulators creates specific compliance requirements that matter for legal, financial services, and public-sector clients. We understand what those clients need from a connectivity provider — KMZ files, physical diversity, documented escalation paths — and we provide it. Lead time: 35 working days via Colt on-net.
Carriers, infrastructure and routing
Proximus is Belgium's incumbent — expanding its fibre network to 42% population coverage by end 2025. For business, their FullFiber Extended offers up to 8.5Gbps download. Telenet provides enterprise internet and 5G with 4G backup. Orange Belgium has nationwide gigabit coverage (95%+ of the Belgian population) and 5G coverage recognised as the best in Belgium in 2025.
Colt is our primary recommendation for enterprise and capacity services in Belgium, with presence at BNIX (the Belgian National Internet eXchange) and a network in Brussels. BNIX (operated by BELNET) is Belgium's central peering hub — PoPs at Digital Realty Zaventem, Colt Brussels, LCL Diegem, and Unix-Solutions. BelgiumIX in Zaventem is a second exchange. Brussels data centres with Google Cloud and Azure direct on-ramps include Digital Realty (BRU1, BRU3, BRU4) and LCL Belgium facilities.
Antwerp's Datacenter United facility is the only Tier IV certified data centre in Belgium — the highest redundancy classification available, relevant for enterprises in the port and logistics sectors with zero-tolerance downtime requirements.
