1. Terms and Definitions

1.1 Message Queue TDMQ: Message Queue TDMQ (Tencent Distributed Message Queue, TDMQ), based on the Apache Pulsar project, is a Tencent Cloud−developed highly reliable distributed cloud message queue. Due to the separated structure of computing and storage, Message Queue TDMQ has good flexibility and malfunction recovery ability, and its open protocol interface supports compatibility with many popular message queues except Pulsar in a plug-in manner.

1.2 Service Month(s): means 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 availability of the Service will be calculated independently for each Service Month.

1.3 Total Time within a Service Month in Minutes: equals to the total number of days of the Service Month × 24 (hours) × 60 (minutes).

1.4 Service Downtime in Minutes: Service Downtime Calculated in Minutes = the time when the Service Unavailability is fixed - the time when the Service Unavailability starts. Service downtime means the time commencing from the malfunction until the recovery of Service, including any unscheduled maintenance time. Service Unavailability that lasts for more than five (5) minute will be counted in the Service downtime. However, when the Service Unavailability is fixed within five (5) minute, which means that the actual downtime of the Service is less than five (5) minute, such downtime will not be counted in the Service downtime defined herein.

1.5 Monthly Service Fee: means the aggregate service fees paid by you for a Message Queue TDMQ service under certain Tencent Cloud account within one (1) Service Month, excluding the portion paid yet to be consumed, and the portion deducted by a voucher or promotional voucher, due to discounted service fee or otherwise deducted.

2. Service Availability

2.1 Calculation of Service Availability

Service Availability = (Total Time within a Service Month in Minutes - Service Downtime within a Service Month in Minutes) / Total Time within a Service Month in Minutes × 100%

2.2 Service Availability

The Service Availability of the Service provided by Tencent Cloud will be no less than 99.95%. You are entitled to the compensation as set forth in Section 3 (Service Compensation) below if the Service Availability fails to meet the aforementioned standard, other than in any circumstance as provided for in the release of liabilities provisions below.

If a Service Month has thirty (30) days, the total available time of Service in such month would be 30 (days) × 24 (hours) × 60 (minutes) × 99.95% = 43178.4 minutes; that is, the Service downtime in such month will be 43200 -- 43178.4 = 21.6 minutes.

3. Service Compensation

In respect of this Service, if the Service Availability fails to meet the abovementioned standard, you will be entitled to compensations in accordance with the following terms:

You cannot use the voucher to purchase other services of Tencent Cloud, nor should you give the voucher to a third party for consideration or for free.

(2) If the Service Availability for a Service Month fails to meet the standard, the amount of compensation will be calculated for such month independently, and the aggregate amount shall be no more than the applicable Monthly Service Fee paid by you for such month (the Monthly Service Fee referred to herein shall exclude the portion deducted by a voucher or promotional credit, due to discounted service fee or otherwise deducted).

3.2 Time Limit for Compensation Application
