We provide new COS users with a limited free tier for STANDARD storage usage up to 6 months. For more information, see Free Tier.
A COS bill is broken down into 5 items: storage usage, requests, data retrievals, traffic, and administrative feature.
For information on billable items in COS and billing rules, see Billing Overview.
Possible reasons include:
You can go to COS Console > Storage Package(https://console.cloud.tencent.com/cos5/package), and check when your storage packs take effect and expire, and how they are used.
Possible reasons include:
Other billable services, such as requests, data retrievals, and administrative feature, are all billed on a pay-as-you-go basis.
2. Fees in other regions:
- COS storage packs are purchased by region, and not shared among regions. For example, assume that you purchased a STANDARD storage pack universal in Mainland China (excluding Finance Cloud regions), and created a bucket in Singapore region, then this bucket is billed on its own, and ineligible for your storage pack.
- Currently, COS offers 2 storage packs: Universal-Mainland China ** and **Universal-Outside Mainland China. Either storage pack applies to the usage of resources only in the region you specify, outside which the resources usage is still billed on a pay-as-you-go basis. For regions, see Regions and Access Domain Names.
You can view information about the fees incurred by COS in the Billing Center in the console. For more information, see Viewing Billing Details.
There are charges for traffic when data transfer happens between COS and CVM from different regions, and no such charges if in the same region (free for data transfer over private network). For more information, see How to determine an access over private network.
All requests generated by data transfer between CVM and COS will be billed.
Public network downstream traffic is traffic generated by data transfer from COS to the client over the internet. Traffic generated by downloading an object directly through an object link or by browsing an object through a static website access node is public network downstream traffic. For more information on billing for such traffic, see Billable Items and Product Pricing.
It may be because you are still using the COS origin domain name formatted as
<BucketName-APPID>.cos.<region>.myqcloud.com to access COS files after you enabled CDN acceleration. We recommend that you use CDN acceleration domain name instead, which only generates CDN origin-pull traffic.
CDN origin-pull traffic is traffic generated by data transfer from COS to a CDN edge server. After CDN acceleration is enabled, traffic generated by browsing or downloading COS data in the client is CDN origin-pull traffic. For more information on billing for such traffic, see Billing Overview and Product Pricing.
No, a COS storage pack takes effect upon purchase and cannot be returned.
Tencent Cloud products within the same region access each other over the private network by default, with no traffic fees incurred. For more information, see How to determine an access over private network.
If your COS service is suspended because your account is in arrears, you have no access to the console. Your data will be retained for 120 days. If you fail to top up your account to a positive balance within this period, your data will be terminated. For more information, see Arrears.
