SUNeVision Holdings Ltd. (SEHK: 1686) is the technology arm of Hong Kong property giant Sun Hung Kai Properties, and it operates as the dominant colocation and carrier-neutral data centre provider in the Hong Kong market under its iAdvantage brand. As of 2025 the company runs eight physical data centres across Hong Kong Island, Kowloon and the New Territories, together representing over 280MW of planned/operational power capacity across roughly three million square feet of gross floor area. Its flagship and fastest-growing property is MEGA IDC, a purpose-built hyperscale, AI-ready campus in Tseung Kwan O that, once fully built out in three phases, will be Hong Kong’s single largest data centre by power capacity. SUNeVision differentiates itself through dense telecom and cloud interconnection — its MEGA-i building alone hosts more than 200 telco carriers, roughly 15,000 cross-connects, and points of presence for nine submarine cable systems, HKIX and major cloud on-ramps like AWS Direct Connect and Microsoft Azure ExpressRoute. The company owns the buildings it operates in, rather than subleasing wholesale space from a third party, and has increasingly pitched its newest capacity (MEGA IDC, MEGA Gateway) toward hyperscale cloud and AI/GPU tenants seeking high-density, resilient power in a supply-constrained Hong Kong market.
SUNeVision has a confirmed data center presence at the following locations:

AI Data Centers
SUNeVision's newest and largest facility, MEGA IDC in Tseung Kwan O, is explicitly built and marketed as an AI-ready hyperscale data centre rather than a general-purpose one. Its first phase delivered about 500,000 sq ft and 50MW of capacity and has already drawn major cloud providers and international banks, while the facility's seven on-site 132kV transformers and reinforced 20kPa floor loading are specifically designed to handle the power density and weight of modern AI/GPU racks. SHKP and SUNeVision executives have publicly framed the project as positioning Hong Kong to support both global and mainland Chinese cloud and AI companies expanding in the Asia-Pacific region.

Common Questions
How many data centres does SUNeVision operate, and where?
As of the March 2025 announcement about MEGA IDC Phase Two, SUNeVision operates a total of eight data centres across Hong Kong: MEGA IDC and MEGA Plus in Tseung Kwan O, MEGA Gateway and JUMBO in Tsuen Wan, MEGA-i in Chai Wan, MEGA Two in Fo Tan, ONE in Kwun Tong, and a leased single-tenant facility in Fanling.
Does SUNeVision have AI/GPU-specific infrastructure?
Yes — its MEGA IDC campus in Tseung Kwan O is explicitly marketed as an 'AI-ready' hyperscale facility, built with seven on-site 132kV/75MVA transformers, a 5.7m slab-to-slab modular design and 20kPa floor loading to support high-density AI and cloud deployments, and the company states it has already attracted major cloud providers and international banks as tenants.
Is SUNeVision a cloud provider or a colocation company?
SUNeVision, through its iAdvantage brand, is a colocation and carrier-neutral connectivity provider — it sells rack, cage and suite space plus interconnection services (including access to public cloud on-ramps like AWS Direct Connect and Azure ExpressRoute) rather than selling its own branded cloud compute or storage service.
Does SUNeVision own the buildings its data centres are in?
For most of its Hong Kong portfolio yes — the company describes an 'owner model of all data centre buildings in Hong Kong,' though its newer Fanling facility is a leased, single-tenant building pre-committed from inception.
