End-of-contract data extraction This is service dependant and also depends on the complexity of the infrastructure services provided. CenturyLink has a standard methodology for the creation of an exit plan for its customers. The costs and timescales are wholly dependent on the size of the infrastructure, the requirements of the customer and the customer needs for the transfer of data back to the customer or its new supplier. A customer can request the return of data on a standard CD format or stored onto unique tape media, encrypted, duplicated and shipped to separate locations.
End-of-contract process CenturyLink has a standard methodology for the creation of an exit plan for its customers. The costs and timescales are wholly dependent on the size of the infrastructure, the requirements of the customer and the customer needs for the transfer of data back to the customer or its new supplier. At a high-level the proposed exit plan methodology, under a statement of work, would be as follows: The contract reaches the point of natural expiry is terminated as per the contract, or another trigger event occurs that requires the implementation of an exit plan. CenturyLink Professional Services / Project Manager will own execution of the plan within CenturyLink. Professional Services / Project Manager discuss with customer exactly what is required of the migration. Professional Services / Project Manager engage the areas of the business required to deliver on the plan. If this exceeds contracted thresholds for exit costs, or is otherwise chargeable under the contract then these charges will be agreed with customer before commencement of the plan. Execute in accordance with the agreed plan.

Using the service

Web browser interface Yes
Using the web interface The Control Portal (https://control.ctl.io) is a web-based graphical interface for managing the core components of the Platform. The Control Portal is categorised as Dashboard, Infrastructure, Network, Orchestration, etc..

What users can and can't do using the API API allows the customer to connect to CenturyLink to create tickets, perform limited updates, and add notes without manual intervention such as calls to the Operations Centre or Account Team. It is a single directional API. As such, the Portal API requires the Customer to schedule “gets” to have updates processed into their system. Therefore, as CenturyLink works to update the ticket, those updates are not pushed back to customer in real time. Creates are performed in real-time and poll intervals are established to ensure system performance. Polls are limited to no more than every minute. Data retrieved may be delayed by 30 minutes. The specifics of this configuration should be finalised through collaboration with CenturyLink.
