This Service Level Agreement (“SLA”) for Hosting Solution sets forth the service levels (“Service Levels”) for the eligible combination of hosting related services (“Hosting Solutions”) provided to Customer within a Data Center. This SLA is subject to and incorporated into the Agreement and the applicable Service Schedule(s) between the parties and any terms not defined in this SLA shall have the meaning set forth therein.
In the event of a Service Level Failure, Customer may be entitled to receive the applicable service credit set forth herein (“Service Credits”).
A Hosting Solution (or “Service”) is eligible for the Service Levels set forth in Section 3 if it consists of at least one Managed Service from each of the following categories: Hosting, Firewall, Load Balancer/SSL Acceleration, Storage and HAN, that is purchased together as an integrated solution approved in writing by CenturyLink and maintained with Full Redundancy as set forth herein.
Hosting Solutions that do not meet the eligibility criteria or Hosting Solutions that are changed and no longer meet the eligibility criteria will not be entitled to this Hosting Solution Service Level. In the event that the Customer’s Hosting Solution loses eligibility for this Hosting Solution SLA, then the CenturyLink Managed Hosting SLA will be applicable to the Customer’s Services. For avoidance of doubt, any Service Credits provided hereunder shall not be combined with the CenturyLink Managed Hosting SLA.
The Hosting Solution add-ons of Managed Applications and CenturyLink Network (as each is described herein) are not required under this SLA but may be added to the solution by mutual written agreement and once added, provided there is Full Redundancy, they are deemed part of the Hosting Solution and subject to this SLA.
An eligible Hosting Solution is provided with an Availability Service Level of 99.9% per calendar month. If Customer’s entire Hosting Solution is subject to an Outage, a Service Level Failure shall be deemed to occur and Customer will be entitled to a Service Credit as follows:
(per Calendar Month)
(per Calendar Month)
(% of Hosting Solution MRC)
|< 99.89% - ≥ 99.80%||> 43.20 minutes – ≤ 1.44 hours||5% credit|
|< 99.80% - ≥ 99.50%||> 1.44 hours – ≤ 3.6 hours||10% credit|
|< 99.50% - ≥ 99.25%||> 3.6 hours – ≤ 5.4 hours||20% credit|
|< 99.25% - ≥ 99.00%||> 5.4 hours – ≤ 7.2 hours||30% credit|
|< 99.00%||> 7.2 hours||50% credit|
Service Credits shall be calculated on only those Managed Services that form part of the affected Hosting Solution.
Customer must request any Service Credit due hereunder by submitting an e-mail to firstname.lastname@example.org within sixty (60) calendar days of the conclusion of the month in which the Service Level Failure(s) occurs. Customer waives any right to Service Credits not requested within this sixty (60) calendar day period. Service Credits will be issued once validated by CenturyLink and applied toward the invoice which Customer receives no later than two (2) months following Customer’s Service Credit request. All performance calculations and applicable Service Credits are based on CenturyLink records and data unless Customer can provide CenturyLink with clear and convincing evidence to the contrary.
The applicable SLA provides Customer's sole and exclusive remedies for any Service interruptions, deficiencies, or failures of any kind. To clarify, such sole and exclusive remedies shall not apply to breaches of unrelated obligations under the Agreement such as infringement, confidentiality, etc. A Service Level Failure shall not occur, the SLA, including any remedies hereunder, will not apply and Customer will not be entitled to receive a Service Credit in the case of an Excluded Event. The Service Credits offered in this SLA shall not be combined with any other CenturyLink SLA for the Services covered herein. Customer will not be eligible to receive any otherwise applicable Service Credits if Customer is in breach or default under any provisions of the Agreement at the time the Service Level Failure(s) occurred or at the time when such Service Credit is requested by Customer until such breach is cured, at which point the Service Credits will be applied. The Service Credits set forth herein are not cumulative and in no event will the Service Credits accrued in any calendar month exceed, in the aggregate across all events, fifty percent (50%) of the MRC for the affected Hosting Solution.
