response time
Average response is not a resolution time or a contractual guarantee. Support scope and response commitments are agreed for each engagement.
Network change automation applies approved modifications through a repeatable process with pre-checks, controlled execution and post-change evidence. Its purpose is to improve consistency, not remove accountability for production decisions. MCI Network Services develops Cisco and Meraki change workflows that keep the affected scope, approval and recovery behaviour explicit, including what happens when only part of a multi-device operation succeeds.
Useful visibility
Monitor service-relevant conditions rather than collecting alerts without ownership.
Controlled change
Keep maintenance, automation and configuration work reviewable and recoverable.
Clear escalation
Connect incidents to the right engineering, provider and business contacts.
Define the change as a service outcome
We begin with the business requirement and the intended network result. A new VLAN, route or access policy needs a target scope, dependencies and acceptance criteria. Automating a list of commands without understanding that outcome can produce a technically successful job that leaves the service unusable.
The design identifies which objects the workflow owns and which must remain untouched. This is important where controllers, templates or other tools manage adjacent settings. A change should not overwrite unrelated configuration merely because the selected interface accepts a larger object than the task requires.

Validate inputs and target selection
Inputs are checked against the approved inventory and design. Addresses, identifiers, interface roles and environment labels can all cause damage if interpreted incorrectly. We use explicit target confirmation and limits so a misplaced value cannot silently turn a site change into a wider estate operation.
The workflow also checks the live prerequisites. Device reachability, supported versions, current configuration and available redundancy may determine whether it is safe to proceed. A failed pre-check should produce a clear stop and explanation, not be ignored because most targets passed.
A useful starting point

A short description of the problem is enough for an initial discussion.
Tie approval to the actual proposed action
The review shows the relevant differences, affected services and intended sequence. Approval is associated with the version of the workflow and the inputs that will be executed. Changes to those elements after review require an appropriate recheck rather than relying on an earlier generic permission.
Emergency changes can use an agreed expedited process, but the authority and record remain clear. The automation should not expand its scope in response to a failure without an approved rule or human decision. A tool’s ability to make a change does not confer the right to do so.
Different environments. The same care.
Built around the work
your network supports.
Finance, banking and the wider private sector. We start with the systems and people that depend on your connections.
Finance & banking
Market-data paths, routing and provider coordination on clients’ behalf.
Financial-market services ↗Offices & multi-site teams
Reliable access between people, workplaces and business applications.
Office network design ↗Data centres & cloud
Network boundaries, workload connections and operational ownership.
Data centre networks ↗Sequence changes by failure domain
Concurrency is selected according to the topology and service risk. Updating redundant peers or several critical paths simultaneously can remove the protection on which the maintenance plan relies. We use staged groups and decision points so the result of one stage is known before the next begins.
The sequence also accounts for dependencies outside the network devices, such as firewall policy, identity systems or provider configuration. Those actions may be performed by other teams. The workflow records their required state and stops when a prerequisite is missing instead of assuming that an external change has happened on schedule.
Handle errors and uncertain results
A multi-device job is not automatically a single transaction. Some changes may have been accepted before communication fails or a later target rejects its configuration. We record individual outcomes and reconcile the live state before retrying operations whose effects are uncertain.
Recovery is designed for the actual task. Restoring an earlier configuration may be appropriate in some cases; other changes require a compensating action or a customer decision. We test the limits of rollback and avoid claiming that a failed automation run guarantees the network has returned to its original state.
Verify the network after execution
Post-checks compare the intended configuration with relevant operational evidence. Routing, authentication, security boundaries or application paths are tested according to the change. A successful API response or command exit status is not sufficient evidence that the service outcome has been achieved.
The workflow stops or escalates when validation fails. It should preserve useful diagnostics and avoid making further speculative changes in an attempt to force a pass. The completion record identifies both successful targets and any targets left in an uncertain or degraded state. Operators receive the information needed to decide whether to continue, recover or investigate a separate fault.
Maintain an auditable implementation process
Deliverables include the reviewed workflow, dependencies, input schema, tests, execution records and recovery instructions. Secrets are protected, and access to change the automation is governed alongside access to run it. Later platform or API updates trigger compatibility review rather than being accepted without testing.
MCI can develop a defined change process within network automation or improve an existing deployment pipeline. The service combines engineering judgement with repeatable execution, helping your organisation reduce manual variation while retaining approval, service validation and a practical response to partial failure.
