3.1. Sustaining Engineering
CenturyLink switches provided as part of EHE Equipment utilize Cisco NXOS and ACI technologies. NXOS is Cisco’s legacy technology for handling network routing and ACI is Cisco’s latest technology, which allows for software-defined capability. Technological capability varies by CenturyLink Managed Hosting data center. The purchase of CenturyLink’s Advanced Managed Services (contracted, ordered, and priced separately) may be required as detailed below based on Customer needs.
The following table shows various automation elements that may vary by region or market. Those supported by ACI will not require CenturyLink’s Advanced Managed Services whereas those supported by NXOS will require it. Maintaining NXOS requires two additional hours per month for automation, upgrades, and sustained engineering respectively, as described in the table below. Additional hours of Advanced Managed Services above the minimum will be billed separately.
|Capability of the Service based on
technology selected by Customer
|ACI||NXOS||NXOS Advanced Managed Services Minimum Hours|
|Automation – provisioning of new network routes||Yes||No (Implemented by Advanced Managed Service team)||2 per month|
|Upgrades – code changes pushed to systems||Upgraded as datacenter gets upgraded||Separate upgrade window needed||2 per month|
|Sustained Engineering – ongoing upgrades to system||Upgraded as datacenter gets upgraded||Separate upgrade window needed||2 per month|
|Integration with CenturyLink’s HAN||Yes||No|
|East/West Traffic – traffic flow of EHE Equipment||Yes – Requires additional gear deployment at Customer expense||Yes|

3.2. Change Management
All changes to the CenturyLink managed applications, systems, network and facilities are subject to CenturyLink’s change management process. This change management process is intended to confirm that changes are reviewed for completeness (risk assessment, completed test procedure, metrics for measuring progress, back out procedure, etc.) and accuracy prior to scheduling and implementation.
CenturyLink compiles, packages, certifies, approves and delivers software patches for installation on the EHE Equipment. Any outages directly caused by Customer's failure to accept the implementation of a patch will not be subject to the EHE SLA, as detailed in Exhibit B.
CenturyLink may periodically upgrade the hardware or the relevant operating software on EHE Equipment to conform with the latest tested and approved versions. If CenturyLink determines an upgrade is necessary, CenturyLink will perform the upgrade during its standard maintenance window. Customer must allow CenturyLink to make these changes within five business days of receipt of the request from CenturyLink, or CenturyLink’s obligation to provide the EHE in accordance with this CenturyLink Service Guide will be suspended until Customer grants CenturyLink the access required to make such changes. If CenturyLink determines that an emergency security change is required, CenturyLink will make the change as quickly as possible. CenturyLink will use commercially reasonable attempts to contact the Customer’s technical contact prior to said change.
CenturyLink does not automatically upgrade every Customer environment. If a newer version of software has been tested and approved by CenturyLink, and the Customer wishes to upgrade, they may proactively request this via a support ticket.

This Service Level Agreement (SLA) applies to the availability of EHE Equipment and Customer’s ability to utilize the EHE Equipment in order to access the applicable Managed Services Node. A Managed Services Node is the location within a data center in which CenturyLink operates and maintains the physical hardware associated with Edge Hosting Services. Service levels do not apply due to Excused Events identified below.
This SLA does not apply to those instances in which Customer provides its own connectivity between the EHE Equipment and the applicable Managed Service Node since CenturyLink does not have the ability to monitor the EHE Equipment.
The service levels applicable to CenturyLink provided connectivity or managed services purchased under separate terms and conditions will apply in addition to this SLA.
Availability. CenturyLink will use commercially reasonable efforts to have (i) the EHE Equipment available; and (ii) Customer be able to access the Managed Services Node99.982% of the total hours in a calendar month (the “Availability SLA”).
“Service Unavailability” refers to a failure of EHE Equipment or Customer’s inability to access the applicable Managed Service Node despite operational EHE Equipment (e.g. failure of CenturyLink provided connectivity or other equipment/hardware within CenturyLink’s control). Customer is entitled to a service credit if one of the Service Unavailability scenarios applies in any calendar month. Service Unavailability is calculated from the timestamp when CenturyLink opens a trouble ticket following the report of a problem by the Customer until the time the ticket is closed. For Service Unavailability, Customer will be entitled to a service credit off the MRC for the affected Service based on the cumulative minutes of Service Unavailability in a calendar month in accordance with the table below.
