索赔
- 对于世纪互联考虑索赔，客户必须在索赔事件发生的月份之后的日历月月底向世纪互联客户支持提交索赔。例如，如果事件发生在 2 月 15 日，世纪互联必须在 3 月 31 日之前收到索赔和所有必需信息。客户必须向世纪互联的客户支持提供所有必要的信息，以便世纪互联验证索赔，包括但不限于：（1）事件的详细描述，（2）关于停机时间和持续时长的信息，（3）受影响的用户的数量和地点（如适用），（4）客户尝试解决该事件所做出的任何努力的说明。
- 世纪互联将合理地运用所有的可用信息来验证索赔，并确定是否就适用服务费抵扣做出决定。世纪互联将在接下来的一个月内，使用商业上合理措施来处理索赔，且时间不超过收到索赔后的四十五（45）天。客户必须遵守本协议，才有资格获得服务费抵扣。如果确定客户适用服务费抵扣，世纪互联会将服务费抵扣应用于客户适用的月服务费中。
- 如果客户购买了多项服务（不是以套件的形式），则客户可以根据上述流程提交索赔，如同每项服务都有其单独的服务级别协议一样。如因同一事件而未满足特定服务的多个服务级别，则客户必须只能选择基于此事件的一个服务级别进行索赔。除非在具体的服务级别协议中另有规定，否则每项服务仅允许在适用的月周期内使用一个服务费抵扣。

Terms
Claims
- For 21Vianet to consider a Claim, Customer must submit the Claim to 21Vianet’s customer support by the end of the calendar month following the month in which the Incident that is subject to the Claim occurs. For example, if the Incident occurred on February 15th, 21Vianet must receive the Claim and all required information by March 31st. Customer must provide to 21Vianet’s customer support all information necessary for 21Vianet to validate the Claim, including but not limited to: (i) a detailed description of the Incident; (ii) information regarding the time and duration of the Downtime; (iii) the number and location(s) of affected users (if applicable); and (iv) a description of Customer’s attempts to resolve the Incident at the time of occurrence.
- 21Vianet will use all information reasonably available to validate the Claim and to determine whether any Service Credits is due. 21Vianet will use commercially reasonable efforts to process Claims during the subsequent month and within forty-five (45) days of receipt. Customer must be in compliance with the Agreement to be eligible for a Service Credit. If 21Vianet determines that a Service Credit is owed to Customer, 21Vianet will apply the Service Credit to Customer’s Applicable Monthly Service Fees.
- If Customer purchased more than one Service (not as a suite), then Customer may submit Claims pursuant to the process described above as if each Service was covered by an individual SLA. In the event that more than one Service Level for a particular Service is not met because of the same Incident, Customer must choose only one Service Level under which to make a Claim based on the Incident. Unless as otherwise provided in a specific SLA, only one Service Credit is permitted per Service for an Applicable Monthly Period.

In cases where Service Levels apply to individual Service Resources or to separate Service tiers, Service Credits apply only to fees paid for the affected Service Resource or Service tier, as applicable.
- The Service Credits awarded in any billing month for a particular Service or Service Resource will not, under any circumstance, exceed Customer’s Applicable Monthly Service Fees for that Service or Service Resource, as applicable, in the billing month.
- If Customer purchased Services as part of a single offer, the Applicable Monthly Service Fees and Service Credit for each Service will be pro-rated. In cases where Customer purchased a Service from a reseller, Customer will receive a service credit directly from its reseller and the reseller will receive a Service Credit directly from 21Vianet. The Service Credit will be based on the estimated retail price for the applicable Service, as determined by 21Vianet in its reasonable discretion.
Limitations
This SLA and any applicable Service Levels do not apply to any performance or availability issues resulting from the following:
- due to factors outside 21Vianet’s reasonable control (for example, natural disaster, war, acts of terrorism, riots, government action, or a network or device failure external to 21Vianet’s data centers, including at Customer’s site or between Customer’s site and 21Vianet’s data center);
- that resulted from Customer’s use of services, hardware, or software not provided by 21Vianet as part of the Services, including, but not limited to, issues resulting from inadequate bandwidth or related to third-party software or services;
- that results from failures in a single 21Vianet Datacenter location, when Customer’s network connectivity is explicitly dependent on that location in a non-geo-resilient manner;
- caused by Customer’s use of a Service after 21Vianet advised Customer to modify its use of the Service, if Customer did not modify its use as advised;
- during or with respect to Previews (as determined by 21Vianet);
- caused by Customer’s use of a Service in a manner inconsistent with the features and functionality of that Service (for example, attempts to perform operations that are not supported) or inconsistent with published documentation or guidance;
- that resulted from Customer’s unauthorized action or inaction or from Customer’s employees, agents, contractors, or vendors, or anyone gaining access to 21Vianet’s network by means of Customer’s passwords or equipment;
- that resulted from faulty input, instructions, or arguments (for example, requests to access files that do not exist);
