Before you buy
When a circuit will not help
Some China problems are not path problems. Rule these out before you compare bandwidth.
Check these first
- The page itself: embedded services that are not offered in mainland China need to be replaced or removed, and a better path does not fix them. The China-readiness scanner lists the third-party resources that may be unreachable.
- Where the content is served: serving content from inside mainland China needs ICP filing and local hosting. We carry the traffic, and your CDN or host handles ICP.
- What the traffic is: for browsing and SaaS, office internet can be enough; plant telemetry and bulk transfer are where dedicated capacity fits.
What a private line does not do
- It does not remove the filing question: cross-border approval and ICP filing depend on the traffic and the entity.
- It does not encrypt traffic by default. If the data needs encryption, run it end to end.
- It does not beat the distance floor. The fiber latency floor shows the physical minimum for a city pair.
Use limits
- Cross-border connectivity is for your company’s internal use. As we read MIIT Circular [2017] No. 32, a line used to serve customers or resell connectivity is a different case from internal use, and carriers that lease international private lines keep records of their users. See the compliance primer.
- We do not publish our peering or interconnection points. A route assessment covers the option, the delivery point and the terms for your traffic.
This is general information, not legal advice. Scope filing and data-transfer steps with your counsel.
Compliance
Cross-border circuits, scoped with your counsel
Cross-border connectivity is provided for your company's internal use. With your counsel, we help you scope the ICP filing and data-transfer steps; this is not legal advice.

What is CloudBond?
CloudBond — premium China routing (AS9929). Measured figures for your city pair and current specifications on request.
Is a cross-border private line into China compliant?
Cross-border connectivity is provided for your company's internal use. With your counsel, we help you scope the ICP filing and data-transfer steps; this is not legal advice.
What is the difference between IEPL and IPLC?
Both are point-to-point international private lines. IPLC (International Private Leased Circuit) is a dedicated Layer 1 circuit; IEPL (International Ethernet Private Line) hands off Ethernet at each end. We recommend one based on your sites, bandwidth and term.
Where can you deliver?
From many regions, with local partners. Tell us your sites and we confirm the nearest delivery point in your quote.
How fast can we start?
We do not promise a fixed lead time. The route assessment comes before the quote, and your sites, the option you choose and the delivery point set the pace, so the timeline depends on your project. Your quote sets it out.
What do you check before a China circuit goes live?
We serve businesses only and verify the company and its use case before activation. Depending on your country, products and use case, we may ask for supporting documents; your quote lists what applies. Your quote also names the contracting company: enterprise connectivity into China answers who signs, and our entities lists our local contracting companies. Our sales, onboarding and support teams work in English; we do not run a Spanish or Portuguese support desk. Where a local company holds your contract, it can support you locally.
