3. Service Credit Calculation

If a Managed Hosting Service, as set forth in Table A of Section 2, or a Managed Application, as set forth in Table B of Section 2, is subject to an Outage, Customer may be entitled to receive a Service Credit as follows:

Availability Service Level Level 1 Level 2 Level 3 Level 4
99.99% Service Level 5 minutes < Outage < 60 minutes 60 minutes < Outage < 3.6 hours 3.6 hours < Outage < 7.2 hours Outage ≥ 7.20 hours
99.90% Service Level 44 minutes < Outage < 3.6 hours 3.6 hours ≤ Outage < 7.2 hours 7.2 hours ≤ Outage < 10.8 hours Outage ≥ 10.8 hours
99.75% Service Level 1.8 hours < Outage < 5.4 hours 5.4 hours ≤ Outage < 9.0 hours 9.0 hours ≤ Outage < 12.6 hours Outage ≥ 12.6 hours
99.25% Service Level 5.4 hours ≤ Outage < 9.0 hours 9.0 hours ≤ Outage < 12.6 hours 12.6 hours < Outage < 16.2 hours Outage ≥ 16.2 hours
98.50% Service Level 10.8 hours < Outage < 14.4 hours 14.4 hours ≤ Outage < 18.0 hours 18.0 hours ≤ Outage < 21.6 hours Outage ≥ 21.6 hours
Maximum Service Credit
(% of MRC for Affected Service)
15% 20% 25% 30%

The Service Credit will be calculated by multiplying the appropriate percentage set forth in the Affected Service Credit row above by the Monthly Recurring Charges for the Affected Service in the month in which the Outage occurred.

“Outage” means the accumulated time in a calendar month during which Customer or any of its users are unable to establish a Session with an applicable System(s) or Managed Application as tracked in an open trouble ticket for reasons other than: (a) a doubling of information transmitted above the committed data transmission rate specified in the most recent Service Order for the Customer if the committed rate is in excess of 10 Mbps; (b) failures caused by any information or content; (c) information or content unavailability caused by ongoing restoration of content or information from a tape backup system; (d) Outage is due to any action on the part of a third party not performing authorized work on behalf of CenturyLink that results in network or equipment outage (including but not limited to viruses, trojan horses, denial of service attack(s) and/or worms); (e) emergency maintenance; or (f) any Excluded Events.

6. Limitations

The applicable SLA provides Customer's sole and exclusive remedies for any Service interruptions, deficiencies, or failures of any kind.
