This SLA is provided pursuant to and in accordance with the governing service agreement between Customer and Savvis Communications Corporation dba CenturyLink and/or its affiliates (“CenturyLink”). The following Service Level Agreement (SLA) is applicable to the CenturyLink Cloud Services listed below that CenturyLink provides through its affiliate Tier, 3 Inc. and makes available to Customer for a fee. The SLA is not applicable to unrelated third parties or third parties lacking a contractual relationship with CenturyLink. The uptime obligations and the resulting SLA credits are applied on a monthly basis unless specified otherwise. CenturyLink will provide 30-days notice for a material diminution of any portion of the SLA.
Public Network: CenturyLink ensures 100% uptime on all Public Network services to Customers located in CenturyLink Cloud data centers. All Public Network services include redundant carrier grade Internet backbone connections, advanced intrusion detection systems, denial of service (DOS) mitigation, traffic analysis and detailed bandwidth graphs. This does not include DOS attacks or other unknown variables that can affect Internet traffic.
Private Network: CenturyLink ensures 100% uptime on the Private Network services to Customers located in our data centers. All Private Network services include access to the secure VPN connection, unlimited bandwidth between servers, unlimited uploads/downloads to servers, access to contracted services, traffic analysis and detailed bandwidth graphs.
Control Portal and API: CenturyLink ensures 99.99% access to the Control portal and API. Access to the Control portal is available via the Public and Private Networks. The Control portal is utilized to fully manage the on-demand IT environments located within the CenturyLink data centers. Control portal access includes ticketing system access, account management, server management, bandwidth management, backup management and other related services.
Virtual Servers: Individual standard servers will deliver 99.99% uptime and hyperscale servers will deliver 99.9% uptime as monitored within the CenturyLink network by CenturyLink monitoring systems. Only failures due to known CenturyLink problems in the hardware, block storage, and hypervisor layers delivering individual servers constitute failures and as such only they are covered by this SLA. Examples of failures include: power interruptions, hardware problems (such as failures to a hard drive or power supply) and failures to the hypervisor environment supporting Customer servers. Problems related in any way to the Customer server operating system or any other software on the Customer server, or to the actions of Customers or third parties, do not constitute failures and as such are not covered by this SLA.
Bare Metal Servers: Individual physical servers will deliver 99.9% uptime. Only failures due to known CenturyLink problems in the hardware constitute failures and such failures shall be categorized as either degraded or unavailable. Degraded services are considered available and therefore not eligible for a service credit. Examples of degraded servers are a single hard drive failure (RAID) or a single DIMM failure. Ticket priorities for degraded servers are set as either high or normal. Physical servers are deemed unavailable for failures of the motherboard, CPU, or multiple drives. Ticket priorities for unavailable servers are classified as high and a service credit, if applicable, will be issued for the total time between a valid Customer notification of the failure to the time that a new server is available. See SLA Credit Claim below.
Managed Operating Systems: Managed Operating Systems will deliver 99.99% uptime on standard servers and 99.9% uptime on hyperscale servers. The managed operating system is considered available as monitored within the CenturyLink network for infrastructure and the ability for Customer to open and log in to a RDP or SSH session at the OS layer. Password lockouts and other security invoked events are excluded and not covered by this SLA. Exclusions to uptime include any actions of Customers or Customer Authorized third parties which negatively impact the availability of Customer server and such actions will not constitute failures and as such are not covered by this SLA.
Managed Applications: Managed Applications will deliver a 99.9% uptime and redundant or clustered Managed Applications will deliver a 99.99% uptime as monitored by CenturyLink Cloud monitoring systems. Only failures due to known CenturyLink Cloud problems in the Application layer delivering individual applications constitute failures and as such, only they are covered by this SLA. If multiple Applications are installed on the same server, only one Managed Application, most impacting will be covered under the SLA.
Relational DB Service: CenturyLink delivers a 99.9% uptime for all single instances of Relational DB Service and 99.99% for all instances with replication. A Service failure occurs when a Customer cannot retrieve data because of problems with hardware and/or software in CenturyLink’s control. Data retrieval issues caused by problems connecting to the service, including without limitation problems on the Internet, do not constitute failures and as such are not covered by this SLA.
Object Storage: CenturyLink delivers a 99.9% uptime on Object Storage. An Object Storage failure occurs when a Customer cannot retrieve data because of problems with hardware and/or software in CenturyLink’s control. Data retrieval issues caused by problems connecting to the service, including without limitation problems on the Internet, do not constitute failures and as such are not covered by this SLA. Customer will receive a service credit for the period of time commencing when a ticket is filed requesting assistance in accessing Customer data until the service is reinstated.
Domain Name Services: CenturyLink delivers a 100% uptime for domain name servers (DNS) on the Dynect network. A period of DNS failure is any time during which 100% of Dynect’s Domain Name Servers simultaneously fail to respond to requests for name resolution. This SLA does not guarantee propagation of DNS data across the Internet or the hosting of secondary DNS service for Customer's primary domain in another location, and it does not guarantee against zone inaccuracies due to operator error.
AppFog Services: CenturyLink delivers a 99.9% uptime for the AppFog services platform. A Service failure occurs when a Customer cannot access their application because of problems with hardware and/or software in CenturyLink’s control. Application availability issues caused by problems connecting to the service, including without limitation problems on the Internet, do not constitute failures and as such are not covered by this SLA.
Simple Backup Service: CenturyLink delivers a 99.9% uptime on Simple Backup Service. A Simple Backup Service failure occurs when a Customer cannot backup or restore data because of problems with hardware and/or software in CenturyLink’s control. Data backup and restore issues caused by problems connecting to the service, including without limitation problems on the Internet, do not constitute failures and as such are not covered by this SLA. Customer will receive a service credit for the period of time commencing when a ticket is filed requesting assistance in accessing Customer data until the service is reinstated.
Network Exchange: CenturyLink delivers a 99.99% uptime on Network Exchange. All Network Exchange services include virtual circuits which pass outbound network traffic from the customers CLC servers and inbound network traffic to the customers CLC servers. A Service failure occurs when an active Network Exchange virtual circuit does not pass outbound network traffic from the customers CLC servers and inbound network traffic to the customers CLC servers because of problems with hardware and/or software in CenturyLink’s control. Exclusions to uptime include any actions of Customers or Customer Authorized third parties which negatively impact the Customer server. For example, but not limited to, actions such as making a firewall change or changing the routing table. Such actions will not constitute uptime failures and as such are not covered by this SLA.
Physical Security: CenturyLink maintains 24x365 on-site security in the data center at all times to enforce CenturyLink’s security policies. Those policies require, among other things that CenturyLink employees, vendors and visitors wear a badge and that authorized visitors who have not been issued a permanent badge leave a valid U.S. driver's license or passport with the guard while in the data center.
Maintenance: At certain times planned maintenance is required on CenturyLink Cloud that can cause service disruption. Maintenance services can affect the Public Network, Private Network, Control portal, Virtual Servers, Cloud Storage, Security and other services. CenturyLink will notify Customer of planned maintenance service and will work with the Customer to resolve any issues that they may have with the maintenance service. CenturyLink will provide at least 48 hour notice to Customers for potentially disruptive maintenance activity via email. Potentially disruptive activity includes maintenance where CenturyLink cannot remove or migrate the live Customer data from the target system but it is expected that the maintenance will have no customer impact. CenturyLink will provide at least 96 hour notice via email to Customers for disruptive maintenance activity that will cause a noticeable outage to Customers.
Support Response Time:
High Priority Tickets: All High Priority Tickets receive a 30 minute time-to-acknowledge for the following categories:
For High Priority issues, Customer must create a ticket for which a tracking number will automatically be provided and a support engineer will review the support request within the timeframe listed above. If for some reason Customer does not receive a response within 30 minutes, Customer should escalate via phone at 1-888-638-6771. CenturyLink Cloud may reclassify any Ticket misclassified as falling into one of the High Priority categories listed above and such Ticket will not qualify for High Priority treatment.
Response times for non-High Priority Tickets are based upon the Customer’s level of support:
Enterprise Support: Less than 30 minutes
Professional Support: Less than 1 hour
Developer Support: Less than 8 hours
Incident Reports:CenturyLink will provide Customer with an Incident Report via e-mail within twenty-four (24) hours for incidents resulting in greater than thirty (30) minutes of downtime. The Incident Report will include: incident date, duration, issue, details of the problem and details of the resolution.
SLA Credit Claim:
"Emergency Maintenance" refers to any corrective action intended to remedy conditions likely to cause severe Service degradation, as designated by CenturyLink in its sole discretion. Emergency Maintenance may include but is not limited to actions intended to address hardware or software failures or viruses/worms. CenturyLink will exercise reasonable efforts to inform Customer in advance before interrupting the Service for Emergency Maintenance, but such notice is not guaranteed and failure thereof does not constitute failure.
Limitations: This SLA provides Customer's sole and exclusive remedies for any Service interruptions, deficiencies, or failures of any kind. To clarify, such sole and exclusive SLA remedies shall not apply to breaches of unrelated obligations under the Agreement such as infringement, confidentiality, etc. This SLA does not cover (without limitation): (a) network performance to Customer's physical location or Internet access point (such as a local DSL/cable modem); or (b) failures due to denial of service attacks.
Credit Issued: For all SLA’s, CenturyLink issues service credits at a credit factor of 45 times the hourly cost for every hour of downtime. The service credit formula is as follows:
Hours of Credit Eligible Downtime x Credit Factor x Product and/or Service Hourly Cost = Service Credit.
For example, a Virtual Server (99.99% SLA) that has a failure lasting 1 hour 45 minutes will be credited as follows:
