Our own 100Gbps+ of local bandwidth connects directly to HKIX, paired with premium CN2 HK–China lines, CDN and global bandwidth to link Hong Kong, the mainland and the rest of the world over a fast, reliable network.
UD is Hong Kong's first cloud hosting company to invest in over 100Gbps+ of its own dedicated local bandwidth, connecting directly to the Hong Kong Internet Exchange (HKIX1 and HKIX1b), with a ring network architecture spanning four data centres to greatly increase throughput.
The ring architecture scales out flexibly and can automatically handle failover and disaster recovery without any IP address changes, backed by an industry-leading "PCI × DR" solution. Overseas, multiple server farms (including US nodes) and global CDN nodes accelerate websites end to end.
Four Hong Kong Tier III+ data centres interconnected in a ring network, any single point of failure fails over automatically, with no business interruption and no IP change.
