Backups and Business Continuity
We provide a high level of cross-regional business continuity to be able to support the worst of disasters.
Backups are cloned over secure links to remote archives. These run daily for non-data-store systems, with data-store systems supporting journals and logs and a Recovery Point Objective (RPO) of 24 hours. Overall Recovery Time Objective (RTO) is 24 hours. Daily backups are retained for seven days, and a weekly backup is retained beyond that for a total period of 90 days.
In most cases, maintenance has limited or no negative impact on the availability and functionality of Lumen’s services.
We intend to provide at least five days' notice in advance of any planned maintenance windows that may impact system availability. However, we may perform emergency unscheduled maintenance at any time. If we expect emergency unscheduled maintenance to negatively affect the availability or functionality of the Application Services, we will do our best to provide advance notice.
Any outage which happens within these defined maintenance windows is not considered a service outage.
Changes are made in a continuous manner, with automated testing and validation. There is also a standard change window.
