any malfunction or configuration adjustment of any network or equipment that is not Tencent Cloud facility.
any Service unavailability attributable to any person other than Tencent Cloud, such as hacker attack or negligence of your third-party supplier.

Upon destruction of a database, no data therein can be recovered.
2.3 Data Migration

Tencent Cloud adopts reasonable technical measures, including without limitation network isolation and access control, to ensure the isolation and invisibility of data and resources of different users.
2.5 Right to Know
(1) The location of data center where data is stored (users may query this by submitting a ticket).
(2) The number of data backups and the location of data center where the backup data is stored (users may query this by submitting a ticket).

Tencent Cloud may, in accordance with the current laws and regulations, and provided that the relevant procedural and formality requirements are fully compliant, disclose certain information, including without limitation operation log of key components, operation records of operation and maintenance personnel and operation records of users, for the purposes of cooperating with supervision and administration, evidence collection and investigations of governmental or regulatory authorities or otherwise.
2.7 Malfunction Recovery Capacity
Tencent Cloud database has failover capacity by default, which means that automatic failover will be triggered, without any action of a user, when any malfunction of a master server occurs, thus ensuring the continuity of the Service provided to you. You may submit a ticket or call customer service for support when necessary.
2.8 Due and Late Payments
With respect to database instances with payments to be settled on a pre-pay basis (annual or monthly plan), Tencent Cloud will provide you with a 7-day service period upon expiry of the term of the database, and will then terminate the Service upon expiry of such 7-day period. You should bear all cloud service fees (if any) incurred during such 7-day period, settle all your payments prior to the expiry of the 7-day period and complete the migration of all your data. Tencent Cloud database system will automatically delete all your data fourteen (14) days following such expiry or termination.
With respect to database instances with payments to be settled on a post-pay basis (pay-per-use), Tencent Cloud will provide you with a 2-hour service period when any payment of your account is overdue and will then terminate the Service upon expiry of such 2-hour period. You should bear all cloud service fees (if any) incurred during such 2-hour period and should timely top up your account to ensure the balance remains more than RMB0. Tencent Cloud database system will automatically delete all your data when the balance of your account remains less than RMB0 for twenty-four (24) hours.
3. Service Compensation
If a user is not able to use Tencent Cloud database in a regular way or is completely unable to access the database due to any malfunction attributable to Tencent Cloud, the user has the right to require Tencent Cloud to compensate for such incident/malfunction. The application for such compensation must be submitted within three (3) months following the month for which the availability of the underlying Tencent Cloud database instance fails to meet the relevant standard, and any application submitted thereafter will not be accepted by Tencent Cloud.
3.2 Standards for Compensation
Duration of malfunction = the time when the malfunction is fixed-- the time when the malfunction starts. The duration of malfunction will be calculated in minutes. Where the duration of malfunction, or an unrounded portion thereof, is less than 1 minute, it will be rounded up to 1 minute. For example, if the duration of malfunction is 1 minute and 1 second, it will be calculated as 2 minutes.
One hundred times compensation for Tencent Cloud database malfunction:
(1) Pre-pay: the compensation will be made by extending the use period of the failed database, extended time = duration of malfunction × 100.
(2) Post-pay: the compensation will be made in the form of voucher, the amount of voucher = daily fee of the failed database / 24 / 60 × duration of malfunction × 100.
