This Service Level Agreement (this “SLA”) is an integral part of your Huawei Cloud Customer Agreement (the “Customer Agreement”). Capitalized terms used in this SLA are as defined in the Customer Agreement unless otherwise stated in this SLA. Should there be any difference between this SLA and the Customer Agreement, this SLA shall prevail.
Huawei Cloud may modify the terms of this SLA from time to time, but will not modify your SLA terms in a way that materially reduces the service level for the period you already purchased; however, if you renew your period of use of the Services, the modified SLA will apply. If you disagree with the modified SLA, you may cease using the Services.
General Terms
1. Definitions
“Service (or Services)” means the cloud service listed below in this SLA.
“Service Cycle” means a natural month.
“Total Time of Service Cycle” means the total minutes during every Service Cycle. The specific calculation method is as follows: number of days× 24 (hours) × 60 (minutes)
“Service Unavailable” will be defined for each Service in the Service Specific Terms thereafter. Service Unavailable does not include the situation that Service is unavailable due to the disclaimers described below and disclaimers in the following Service Specific Terms.
“Service Unavailable Duration” means all the time when the Service is unavailable during a Service Cycle. If the duration is less than one month, it is still regarded as one month. Service Unavailable Duration cannot be calculated more than once. The Service Unavailable Duration for each service cycle shall not be included in the Service Unavailable Duration of the next service cycle.
“Service Availability” means during a Service Cycle, the service available percentage per Service Cycle achieved by the Service given in this SLA.
“Monthly Service Fee” means service fees paid by customers for the Service in a Service Cycle. For example, if the customer pays the service fee of several months at a time, the Monthly Service Fee is calculated as the total service fees paid divided by the total number of months.
2. Service Credit
Service Credit: In the event Huawei Cloud does not meet the commitment on the Service Availability Rate specified in this SLA, you will be eligible to receive service credit as described below, which is the sole and exclusive remedy for any performance or availability issues for any Services under the Customer Agreement and this SLA.
Time limit for application: You can apply for service credit in each Service Cycle after the bill is settled. The application must be filed within two (2) months after the end of the Service Cycle in which the incident that is the subject of the claim occurred. Applications beyond the time limit will not be accepted. Huawei Cloud will conduct a reasonable assessment of the application and make a decision on whether compensation is applicable based on the terms of this SLA and the principle of good faith.

TaurusDB Service Specific Terms
1. Definition
Service Unavailability means the TaurusDB system log shows that a DB instance was inaccessible for one (1) or more consecutive minutes because of HUAWEI CLOUD. Duration of the inaccessibility and inability that lasts for shorter than one (1) minute shall not be included.
2. Disclaimers
Service unavailability caused by the following situations shall not be counted in the service unavailability period:
1) Customer operations, such as rebooting, deleting, or restoring TaurusDB instances through the console or APIs;
2) Network faults, device faults, or configuration adjustment of non-Huawei devices;
3) Faults that occur due to single-AZ deployment, instead of multi-AZ deployment;
4) Hacker attacks on customer applications;
5) Planned system maintenance, such as cutover, maintenance, upgrade, and fault drills, of which Huawei Cloud has notified the customer in advance;
6) Data (including passwords) leakage or loss due to improper maintenance of the customer;
7) Operations authorized by the customer or any misjudgment in operations;
8) Customer failure to comply with TaurusDB documentation or recommendations;
9) Service interruptions caused by insufficient vCPUs, memory, storage, and maximum number of connections of a DB instance or proxy instance due to heavy workloads of the customer;
10) Faults caused by open-source community bugs or other non-Huawei Cloud issues;
11) Service suspension or termination due to the customer's breach of service clauses (such as arrears);
12) Customer failure to rectify known problems or risks which Huawei Cloud has notified them of;
13) Unavailability due to the customer's improper use of HTAP nodes;
14) Other force majeure factors.
3. Service Availability
Service Availability Rate in Each Service Cycle calculation formula:
Service Availability Rate in Each Service Cycle = (Total Time of Service Duration - Service Unavailable Duration)/Total Time of Service Duration x 100%.
Service Availability Rate commitment:
HUAWEI CLOUD will use commercially and technically reasonable efforts to make the Service Availability Rate of TaurusDB per Service Cycle be no less than 99.99%.
Remarks: HUAWEI CLOUD cannot ensure the high availability of a single-node DB instance (with a primary node or a HTAP read replica) because the instance is deployed on only a single server.
4. Service Credit
If we fail to meet the commitment above on TaurusDB Service Availability Rate, HUAWEI CLOUD will provide you with service credit as follows.
| Service Availability Rate | Service Credit |
| 99% ≤ Service Availability Rate < 99.99% | 10% of Monthly Service Fee |
| 95% ≤ Service Availability Rate < 99% | 25% of Monthly Service Fee |
| Service Availability Rate < 95% | 100% of Monthly Service Fee |
