1. Terms and Definitions
1.1 Cloud Object Storage, COS
COS provides large-scale Web API storage services, where you can call HTTP RESTful APIs to upload, download, and manage data. It features automatic scaling and is available on a prepaid or postpaid basis.
1.2 Service Month(s)
Service Month(s) refers to the calendar month(s) within the term of the Service purchased by you. For example, if you purchase the Service for a term of three months starting from March 17, there will be four (4) Service Months (the first Service Month from March 17 to March 31, the second from April 1 to April 30, the third from May 1 to May 31, and the fourth from June 1 to June 16). The Service Availability (as defined below) will be calculated separately for each Service Month.
1.3 Error Rate per 5 Minutes
Error Rate per 5 Minutes is the ratio of the number of Failed Request(s) (as defined below) returned by COS to the number of Customer’s total request(s) in 5 minutes. It is calculated as follows:
1.4 Failed Request(s)
Refers to request(s) with error codes indicating server internal errors, including Internal Error (500 error) or Service Unavailable (503 error). However, the following situations are not included:
1. Requests generated by calling the GetService API to retrieve the bucket list.
2. Requests that are executed asynchronously on the backend due to the configuration of cross-region replication and lifecycle rules.
3. Requests that timeout in the process of mirroring back to the origin station.
4. Requests that timeout during the callback process.
5. Requests that timeout during the UDF process.
6. Requests that are rate-limited due to triggering frequency control
7. Failed requests due to COS upgrades, changes, downtime.
8. Requests made with unverified identity, failed authentication, or service suspension due to unpaid bills.
9. User requests to COS resulting from hacker attacks.
1.5 Monthly COS Service Fee
Monthly COS Service Fee refers to the charges incurred by a user's Tencent Cloud account for using Tencent Cloud Object Storage services, including storage capacity, data transfer, requests, data retrieval, or other storage management fees within a natural month.
2. Service Availability
2.1 Calculation Method for Service Availability
Cloud Object Storage calculates the service availability of different storage types based on account and region. For the same account in the same region, the service availability of storage buckets and objects of the same storage type will be calculated together. The service availability of Cloud Object Storage is calculated as follows:
(Note: Total Number of 5-minute units within Service Month(s) = total number of days within Service Month(s) × 24 (hours) × 12)
2.2 Service Availability Standard
You can upload, download and manage data through the API, SDK, console or customer tools provided by Cloud Object Storage. For different storage types, Tencent Cloud promises that the Service Availability of COS will not be lower than the following standards:

MAZ_STANDARD_IA

MAZ_INTELLIGENT_TIERING
The service availability varies with the storage tier. In the high-frequency access tier, it may refer to MAZ_STANDARD; in the low-frequency access tier, it may refer to MAZ_STANDARD_IA.
