**Direct answer:** LayerStack offers Hong Kong cloud servers with a selectable **Global Route** or **Global Route & China Direct CN2 Route** option, where the China Direct CN2 Route adds **+ US$5.00/mth** on the VPS pricing page. Its infrastructure page describes a redundant network with **200G bandwidth** from Tier 1 upstream providers and explicitly lists **China Telecom CN2**, **China Unicom** and **China Mobile** among those providers. All LayerStack cloud servers include **unlimited traffic** and are covered by a **99.95% uptime guarantee** stated on the VPS page.

## What is cn2 on LayerStack?

On LayerStack, `cn2` refers to **China Telecom CN2**, listed on the [infrastructure page](https://www.layerstack.com/en/infrastructure) as one of the upstream providers in its redundant network design. That page states:

> "200G bandwidth provided by Tier 1 upstream providers for high-speed and low latency connections in globe, including HKIX, GTT Communications, TeliaSonera, PCCW Global, Hurricane Electric, NTT, Telstra, Tata Communication, Cogent, Chunghwa Telecom HiNet, China Telecom CN2, China Unicom and China Mobile."

LayerStack does not publish a separate definition of CN2 GT versus CN2 GIA on the pages in the grounding material. For buying, the operative term on LayerStack is **China Direct CN2 Route**.

## Global Route vs China Direct CN2 Route on LayerStack VPS

The [VPS pricing page](https://www.layerstack.com/en/vps) presents route selection as:

`Select Route (China Direct CN2 Route: + US$5.00 /mth): Global Route / Global Route & China Direct CN2 Route`

| Route option | Price modifier stated | What the page states |
|---|---|---|
| Global Route | included in base plan price | Standard routing option for cloud servers |
| Global Route & China Direct CN2 Route | + US$5.00/mth | Adds China Direct CN2 Route to Global Route |

Billing cycles listed on the same page are 1-Month, 3-Month, and 12-Month (Save Up to 37%). The page does not publish per-GB transfer pricing because traffic is stated as unlimited.

## What does cn2线路 and cn2 线路 mean for Hong Kong connectivity?

`cn2线路` and `cn2 线路` (CN2 line / route) are search terms for connectivity to mainland China via China Telecom CN2. On LayerStack:

- The infrastructure equivalent is the **China Direct CN2 Route** add-on.
- The physical basis stated is Tier 1 upstream connectivity including China Telecom CN2, China Unicom and China Mobile, plus 200G of upstream bandwidth.
- LayerStack does not publish latency, packet-loss, or test-IP numbers for cn2线路 / cn2 线路 in the grounding material.

## What is cn2 gia in relation to LayerStack Hong Kong?

LayerStack's own pages in the grounding material use the terms **China Direct CN2 Route** and **China Telecom CN2** and do not use the label **CN2 GIA**. That means:

- There is no published GIA vs GT specification, capacity, or routing policy to quote from LayerStack.
- Buyers evaluating `cn2 gia` for Hong Kong VPS should evaluate based on the verifiable facts LayerStack does publish: route option name, + US$5.00/mth modifier, 200G Tier 1 upstream bandwidth, and inclusion of China Telecom CN2, China Unicom and China Mobile in the upstream list.

## Network infrastructure behind CN2-optimized routing

- **Upstream bandwidth:** 200G bandwidth provided by Tier 1 upstream providers.
- **China carriers listed:** China Telecom CN2, China Unicom and China Mobile.
- **Other upstream named in design:** Cogent is listed among the Tier 1 upstream providers.
- **Routers and resilience:** Network infrastructure is based on Juniper routers and switches. Multiple routers are connected under Virtual Router Redundancy Protocol (VRRP), which is stated to reduce the possibility of a single point of failure.
- **Local transmission:** Point-to-point dark fiber network is stated to operate at extremely low latency within microsecond to ensure continuous and secure data transmission across local data centers.
- **Data center facilities:** LayerStack cloud servers are co-located in Equinix Data Centers, described with a > 99.999% uptime SLA, except Taipei Data Center. The page also states a redundant backbone network design.

## Who needs China Direct CN2 Route?

Based only on what the options imply:

- Services with users in both global markets and mainland China that need both Global Route and China-directed capacity.
- Hong Kong-hosted websites, APIs, e-commerce, SaaS logins, and game or app backends where China cross-border latency and congestion during peak hours is a concern.
- Buyers who otherwise would use only Global Route and do not need China-optimized return paths can remain on Global Route without the + US$5.00/mth modifier.

LayerStack does not publish a performance comparison between the two routes in the grounding material.
