IDC colocation
across 31 licensed cities
Colocation quotes are hard to compare because the same word covers very different things. Fredyun quotes the four cost lines separately — space, power, bandwidth and one-off work — so you can put proposals side by side and see what actually differs.
What this service covers
Rack and cabinet colocation
Scarce rack capacity in tier-one and surrounding cities, elastic expansion, high-tier facilities.
Three-carrier bandwidth
Access from all three Chinese carriers with dynamic BGP routing for a consistent end-user experience.
Managed IT operations
24/7 intelligent monitoring, security hardening, development and managed operations.
Network security and DDoS
DDoS mitigation, network monitoring and traffic scheduling for resilient deployments.
Flexible footprint
Full racks, half racks and single-U colocation — start small and grow without changing provider.
Interconnect ready
Combine with dedicated lines and cloud connect so racks, sites and cloud regions sit on one fabric.
Who uses it, and for what
Compute placement and international egress
- Colocation with three-carrier bandwidth
- Egress split by region — APAC and Europe/Americas steered separately
- Combine with cloud connect so cloud and racks share one fabric
- Optional DDoS mitigation
Colocation with off-site DR
- Racks in separate cities interconnected by dedicated lines or dark fibre
- Dedicated, physically isolated bandwidth for replication
- Supports business-continuity design
- Licensed operation with MLPS and ISO certification
Production data landing and analytics
- Colocation receives production data for analysis
- Dedicated backhaul from plants, bandwidth not shared
- Cloud connect bridges edge and public cloud
- 24/7 NOC monitoring and proactive alerting
Capacity and distribution
- Colocation for content and compute
- CDN distribution nationwide, within licence scope
- Temporary bandwidth for events, from one day
- 10 Mbps – 100 Gbps, upgradable in steps
Service parameters at a glance
These are network-wide figures. Anything that depends on a specific site — facility conditions, access method, exact schedule — is confirmed by survey.
| Item | Specification |
|---|---|
| Footprint | Full rack, half rack or single-U colocation |
| Power | Specified against facility conditions and equipment power density during solution design; high-density kit needs rated power figures up front |
| Network | Three-carrier bandwidth access; 10 Mbps – 100 Gbps; can join dedicated lines and cloud connect on one fabric |
| Coverage | Licence scope covers IDC across 31 cities; nine cities carry Fredyun's own backbone and directly deliverable rack capacity |
| Lead time | Same-day installation where space already exists; otherwise confirmed after survey where new access, special power or floor loading is involved |
| Billing | Per rack or per U plus power, bandwidth access charged separately; installation labour, equipment handling and inter-facility moves listed as one-off items |
| Bandwidth | 10 Mbps – 100 Gbps, upgradable in steps |
| Service assurance | PoP-to-upstream-ISP availability 99.99%; end-to-end link availability 99.5%; 24/7 NOC monitoring and proactive alerting; 100% VIP fault tracking |
| Contract term | Flexible — no blanket minimum. Annual terms for steady services; short-term needs (events, exhibitions, temporary projects) from one day |
| Footprint | 60+ PoPs across Greater China, 120+ PoPs worldwide; measured latency between nodes is queryable on the coverage map |
How to think about it
Power is where quotes diverge. "A rack" says nothing about how much power it carries. Ask three things of any provider: how much supply capacity is included, how the excess is charged (stepped tiers or metered), and whether billing follows contracted capacity or actual draw. Stepped tiers can produce sharp jumps right at the boundary.
Power density is a hard limit. High-density kit — GPU servers, dense blades — can exceed a facility's per-rack design ceiling. Physical space being available does not mean the cooling is. Bring an equipment list with rated power to the survey rather than discovering this after shipping.
Bandwidth is not one product either. Dedicated bandwidth is yours at any moment. Shared-pool bandwidth with a committed rate behaves differently at peak. Ask for the committed rate and the loss and latency numbers that go into the SLA, then compare. Fredyun bills colocation per rack or per U plus power, with bandwidth access charged separately and one-off items listed individually in the proposal.
Licence scope
International and Hong Kong / Macau / Taiwan capacity is not built by Fredyun. China Mobile International (CMI), China Unicom Global (CUG) and China Telecom Global (CTG) hold the international telecom licences and supply the underlying circuits. Fredyun procures that licensed capacity and delivers convergence, routing, end-to-end provisioning and operations on top of it.
Fredyun itself holds a trans-regional value-added telecom business licence (B1-20235481) issued by China's Ministry of Industry and Information Technology, covering IDC, ISP, CDN and domestic internet VPN — trans-regional, not international. This boundary is stated explicitly in every proposal and contract.
What clients ask most
What does a rack cost per month?
There is no single answer, because the total is driven by space, power and bandwidth together — and power alone can double it. Facility grade (power and cooling redundancy, network neutrality) moves the number too. The useful approach is to fix your equipment list, power draw, bandwidth needs and city first, then ask providers to quote against one common definition. Fredyun quotes per rack or per U plus power, with bandwidth separate, after a survey.
I only have one or two servers — do I need a whole rack?
No. Single-U colocation (1U, 2U, 4U) exists for exactly this, billed per U plus power and far cheaper than a full rack. Past a certain equipment count a half or full rack becomes better value; the crossover can be worked out during solution design.
How fast can equipment be installed?
Same day where suitable space already exists. Where a new access segment, special power or floor-loading work is required, the schedule is confirmed after the survey. Providing an equipment list with rated power early lets the survey and space reservation run in parallel.
Can colocation and networking be bought together?
Yes, and it is usually the better plan. Colocation lands the compute, dedicated lines connect it to offices or other facilities, and cloud connect brings public cloud onto the same fabric — designed as one solution, monitored from one portal, with a single accountable party when something breaks.
What is the minimum term?
Flexible, with no blanket minimum. Steady services are typically annual; temporary requirements can be billed from one day. Expansion and downgrade rules are worth agreeing at signature so business changes are not blocked by the contract.
