Database Server Software 1.0 is a Managed Hosting product. The standard “Service” consists of the licensing, installation, configuration, administration, monitoring, maintenance and support for software components.
Customer chooses the Database type, edition, version and options at the time of purchase.
Licensing of the Database Software can either be provided by CenturyLink or obtained by Customer.
If provided by CenturyLink, CenturyLink will, as part of the Service, obtain and maintain the required Software licenses under the Software Vendors Use Rights and License Agreement. All users of the Service are subject to the terms and conditions of the referenced license agreements.
If provided by Customer, Customer may obtain, and maintain throughout the Service Term, the required Software licenses. If Customer chooses to obtain the licenses, CenturyLink will install the Software as part of the Service provided Customer secures and grants the applicable accesses to CenturyLink to allow CenturyLink to perform the Service. Customer shall at all times comply with any and all end user license agreements related to the Software. Customer represents and warrants that a written license agreement exists with the License vendor that permits CenturyLink to perform activities described in the proceeding sections. Customer agrees to provide CenturyLink with evidence of licensing as requested prior to the deployment date and periodically as requested to update the status of the license. If Customer fails to provide the license agreement, CenturyLink may, at its option, delay the deployment date or terminate the Agreement.
If any third party software, including any corresponding documentation, is provided to Customer by CenturyLink in connection with the Service, Customer agrees to be bound by any additional licensing terms and conditions applicable to such third party software and that it will use such third party software strictly in accordance with such terms and conditions. CenturyLink makes no representations or warranties whatsoever with regard to such third party software.
Except as otherwise provided by mandatory applicable law without possibility of contractual waiver and notwithstanding anything in the Master Service Agreement or elsewhere, CenturyLink and its affiliated companies shall not be liable to Customer or indemnify Customer for any claims of infringement of patent, copyright or other intellectual property right related to third-party software components.
The Service Level Agreement (SLA) associated with this Service Guide is the Managed Hosting Services SLA.
CenturyLink SLA applies to all vendor supported configurations. Any configuration or version identified as “unsupported” by vendor will be subject to reasonable effort support by CenturyLink and will not be subject to SLA Service Credits.
CenturyLink utilizes CIS Level 1 security benchmarks and NIST for additional security standards when deploying Managed Database Services and will provide security policies for Managed Database Services to Customer upon request.
CenturyLink will enable application level monitoring for each environment as they are created within the product configuration.
CenturyLink will retain primary notification and resolution responsibilities for all automated environment alerts. A Customer technical contact will be engaged to perform primary resolution of incidents associated with a non-production level environment.
All changes to the CenturyLink managed applications, systems, network and facilities are subject to CenturyLink’s change management process. This process is intended to confirm that work is reviewed for completeness (risk assessment, completed test procedure, metrics for measuring progress, back out procedure, etc.) and accuracy prior to scheduling and implementation.
Major and Minor Releases require a new installation of the Software binaries, which is not included in this Service. CenturyLink suggests that Customer purchase a new managed server (via a Service Order) and migrate data (defined in a SOW) as a commercially reasonable practice.
All times listed under Scheduled Maintenance Windows are local times and subject to change. CenturyLink will use commercially reasonable efforts to perform routine maintenance only during the Saturday or Sunday defined maintenance windows. See Maintenance Windows page for details.
CenturyLink will provide support for the Service during installation, content migration, Customer validation, and 24x7 monitoring and management by the CenturyLink Service Center after installation.
Customer will designate and maintain a Customer Contact during the Service Term (including current contact information). “Customer Contact” means a technical point of contact available 24x7 with sufficient knowledge, authority and access to address configuration issues, event notifications, system or infrastructure modifications and authentication of applicable CenturyLink systems.

If Customer provided licensing, Customer represents and warrants that a written license agreement exists with Oracle MySQL that permits CenturyLink to perform activities described in the proceeding sections.
MyISAM: MySQL non-transactional storage engine
InnoDB: MySQL transactional storage engine
Customers are given login access and access to Httpd directories but not root or sudo access.
CenturyLink compiles, packages, certifies, approves and delivers Software patch versions for installation in a Customer environment. Customer must approve the installation by contacting CenturyLink support. Any Outages directly caused by Customer's failure to accept the implementation of a patch will not be subject to SLA Service Credits.
Customer may increase database availability by purchasing CenturyLink optional Managed Replication Service; MySQL Replication or MySQL Read-Only Replication. The Managed Replication Service includes replication setup, enabling replication session monitoring, and managing failover and fail-back. The supported replication product is statement-based replication. Any other methods (including row-based) can be supported via a Statement of Work (SOW).
Customers may elect to use a tool called MySQL Enterprise Monitor. This tool is a virtual DBA assistant that can help the customer manage more MySQL servers, tune those servers as well as fix problems that arise.
