Article 1 General Provisions

China Telecom  ("CTG" or "Party B", at www.esurfingcloud.com) provides Distributed Message Services for Redis (hereinafter referred to as the "Services") to the Customer (also referred to as "Party A") in accordance with the provisions of the Service Level Agreement (the "SLA") and operating rules issued by Party B from time to time. Party B reserves the right to amend the terms of the SLA at any time.

Article 2 Service Commitment

Party B warrants a service availability rate not lower than 99.95% per Service Cycle for the Services.

Service Cycle: One Service Cycle is one month. If the Customer uses the Services for less than one month, it will not be deemed to have used such Services for one Service Cycle. Unless otherwise specified, one month means 43,200 minutes (i.e. 30 days*24 hours*60 minutes).

Service Unavailability Duration in Minutes: As indicated by the logs in the DCS system, where a complete suspension of the Services persists for more than one minute due to any reason attributable to CTG, the Services will be deemed unavailable for that very minute, while any unavailability persisting for less than one minute will not be considered for the purpose of calculating Service Unavailability Duration.

Calculation of Service Availability Rate per Service Cycle: Service Availability Rate per Service Cycle = (the aggregate time of the Service Cycle - the aggregate time of Service Unavailability of the Service Cycle) / the aggregate time of the Service Cycle x 100%.

Service Commitments: Party B warrants a service availability rate not lower than 99.95% per Service Cycle for the Services.

Article 3 Service Credit as Compensation

Compensation mode: If CTG fails to fulfill its service availability rate commitment under the SLA, the Customer will be entitled to request compensation therefor in accordance with the SLA. Such compensation provided in the form of service credit in service minutes will be the sole and exclusive remedy offered to the Customer by CTG for its failure to fulfill its service availability rate commitment hereunder.

Time limit for request: For each Service Cycle, the Customer may, upon the settlement of the invoices therefor, submit a request for compensation with respect to the cloud services that fail to meet the service availability rate commitment, provided that such request must be submitted within two (2) months from the end of the Service Cycle during which the failure that is the subject of the Customer’s request occurs. Any late request beyond such time limit will not be accepted. CTG will, in accordance with the SLA, evaluate the Customer’s request in a reasonable manner and decide whether the Customer is eligible for such compensation in good faith.

How to request compensation: The Customer may request compensation by submitting a ticket via the customer center of CTG.

Service Credit as Compensation: If CTG fails to meet its service availability rate commitment with respect to the Services, it will compensate the Customer as follows:

Party B is not liable for its failure to perform its commitment hereunder due to any cause of exclusion specified in the preceding paragraphs. Where a Party fails to perform this agreement in whole or in part due to a force majeure event, during the time such Party is prevented from performing the provisions hereof affected by such event, such Party will not be held liable for not performing the provisions within the scope of the impact of such force majeure event, provided that a written notice is served on the other Party. The Parties agree to use their best efforts to resume performance hereof once the cause of such exclusion has been corrected and remedied.
