Offering name	Offering code	Billable item
Cloud Data Transfer - Internet	`cdt_internet_public_intl`	`ECS_Out_Bytes` (ECS outbound internet traffic) `Eip_Out_Bytes` (EIP outbound traffic) `clb_out_bytes` (Classic Load Balancer (CLB) outbound traffic) `Cbwp_Out_Bytes` (Internet Shared Bandwidth outbound traffic) `Cbwp_Max_Bytes` (Internet Shared Bandwidth peak bandwidth) `IPv6_Out_Bytes` (IPv6 Gateway outbound traffic) `GA_Max_Bytes` (Global Accelerator peak bandwidth) `Fc_Out_Bytes` (Function Compute outbound traffic) `MSE_Out_Bytes` (Microservices Engine outbound traffic) `PAI_Eas_Out_Bytes` (PAI-EAS outbound traffic) `Anycast_Max_Bytes` (Anycast EIP peak bandwidth) `nativeapigw_Out_Bytes` (API Gateway outbound traffic) `Miniappdev_Out_Bytes` (Mobi App outbound traffic)

Query bills

View CDT 2.0 bills

Go to the Billing Management > Bill Details page and filter by the following conditions:

Product Name: Cloud Data Transfer
Commodity Name: Cloud Data Transfer
Bill Generation Date: Select the month that you want to query.

After applying the filters, you can view all CDT 2.0 bill details. Use the billable item code column to distinguish between internet data transfer (internet_traffic) and cross-region data transfer (inter_region_traffic).

View CDT 1.0 bills

Go to the Billing Management > Bill Details page and filter by the following conditions:

Product Name: Cloud Data Transfer
Commodity Name: Cloud Data Transfer - Internet or Cloud Data Transfer - Cross-region
Bill Generation Date: Select the month that you want to query.

In CDT 1.0 bills, use the billable item name column (e.g., "ECS Fixed Public IP Traffic Fee", "IPv6 Pay-by-traffic") to identify the source cloud product directly.

View internet traffic costs by product

For CDT 2.0, after filtering for CDT 2.0 bills, locate the rows where the billable item code is internet_traffic. Check the "Resource Type" in the list price factor field to identify the source cloud product. For example:

Resource type: ECS instance → ECS outbound internet traffic
Resource type: EIP → EIP outbound traffic
Resource type: Internet Shared Bandwidth instance → Internet Shared Bandwidth outbound traffic

To aggregate costs by cloud product, export the bill as a CSV file and group the data by resource type.

For CDT 1.0, the source cloud product is identified directly from the billable item name column without parsing the list price factor. For example:

Billable item name: ECS Fixed Public IP Traffic Fee → ECS outbound internet traffic
Billable item name: IPv6 Pay-by-traffic → IPv6 outbound traffic
Billable item name: Anycast Internet Traffic → Anycast EIP outbound traffic

View cross-region traffic costs by region

After filtering for CDT bills, focus on the cross-region billable items:

For CDT 2.0, locate the rows where the billable item code is inter_region_traffic.
For CDT 1.0, focus on the billable items under the Commodity Name "Cloud Data Transfer - Cross-region" (such as CDTIR_Out_Bytes and AnycastInterRegionTraffic).

Use the Region and the region information within the list price factor to view the cost distribution of data transfers between different regions.

What is not changing

Item	Description
List price	Unit prices for all regions and traffic types remain the same.
Free tier	The 220 GB monthly free tier for outbound internet data transfer remains in effect.
Tiered pricing	Tiered pricing aggregation logic, which combines usage from all cloud products, is unchanged.
Resource plan	Existing CDT resource plans are compatible with both CDT 1.0 and CDT 2.0. You do not need to purchase new ones.
Cost allocation	Cost allocation logic remains the same: pay-by-traffic items are allocated using tags, and pay-by-bandwidth items are allocated through cost bills.

FAQ

Will my costs increase after the upgrade?

No. CDT 2.0 only changes the offering structure and bill display. The list price, tiered pricing rules, and free tier remain unchanged, so your bill amount is not affected by this upgrade.

Do I need to take any action for this upgrade?

No action is required. Starting May 20, 2026, new users use CDT 2.0 by default. Existing CDT 1.0 users are upgraded automatically in batches with no service impact.

Identify source product for costs

For CDT 2.0, check the "Resource Type" information in the list price factor field. For example, "Resource Type: ECS instance" indicates the cost is from an ECS instance, and "Resource Type: EIP" indicates it is from an EIP.
For CDT 1.0, you can directly identify the cloud product by the billable item name, such as "ECS Fixed Public IP Traffic Fee".

How to identify the free tier

For CDT 2.0, use the Fee type column. A value of "Free Quota" indicates free traffic, while "Pay-As-You-Go Fee" indicates paid traffic.
For CDT 1.0, use the list price factor column. If it contains "Traffic Tier: Monthly Free Internet Traffic", the traffic is free.

Can I still use my existing CDT resource plans?

Yes. CDT resource plans are compatible with both CDT 1.0 and CDT 2.0. You do not need to purchase new plans, and existing deduction rules remain unchanged.

Do my automation scripts need to be modified?

You may need to update your scripts. The offering codes and billable item codes have changed in CDT 2.0. If your scripts have hard-coded CDT 1.0 values such as the offering code cdt_internet_public_intl or the billable item code ECS_Out_Bytes, update them after the upgrade. We recommend supporting both old and new formats during the transition period.
