Cloud network disaster recovery prepares the paths needed when services move to an alternative site or cloud setup. We design and test Cisco and Meraki routes and access rules as part of the wider plan. Restoring data, identity and apps remains separate work. The recovery network must be reachable when those teams need to use it.
The whole path
Understand how sites, providers, cloud networks and security controls fit together.
Resilience that can be tested
Separate a second circuit from genuine end-to-end service resilience.
Provider coordination
Keep addressing, routing and escalation ownership clear across organisations.
Begin with the application's recovery sequence
We establish which services are expected to recover, where they will run and the order in which their dependencies become available. Network needs follow that sequence. A recovery server may need DNS, identity, licensing and management access before users can connect, even when its main app port is reachable.
The customer's continuity owner defines the recovery aims and acceptable reduced service. MCI identifies the networking contribution and dependencies, rather than promising an app recovery time based only on a router or tunnel test. Responsibilities for data restoration, workload startup and business validation remain clear.

Map the alternative addressing and routes
The recovery setup may use different prefixes, gateways or public addresses from the normal service. We document those differences and their effect on branch routes, cloud route tables, firewalls and external counterparties. Address overlap between primary and recovery setups can create ambiguity if both become reachable at once.
The design also identifies how traffic is directed to the recovered service. DNS, routing changes and app setup may each have a role. We avoid assuming that one route advertisement updates every consumer, especially where a partner uses a fixed address or an external allowlist requires separate approval.
A useful starting point

A short description of the problem is enough for an initial discussion.
Ensure security follows the recovered workload
Recovery should preserve the required access boundaries, not merely restore network access through a broad temporary permit. We map the relevant segmentation, inspection and admin controls in the alternative setup. A standby site that has never received current policy may behave very differently from the production setup it is intended to replace.
Privileged recovery access is planned separately from ordinary user access. The team needs a controlled way to operate when central identity or management services are unavailable. Emergency credentials and permissions have owners, storage needs and a review process, rather than being distributed widely in an unrestricted recovery document.
Different environments. The same care.

Finance, banking and the wider private sector. We start with the systems and people that depend on your connections.

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 ↗Examine shared dependencies that could defeat recovery
Primary and recovery paths may still depend on the same provider, DNS service, cloud region, virtual appliance or admin account. We identify those shared elements and assess whether they match the failure scenarios the business is planning for. A second tunnel is not an independent recovery solution if it terminates on the same failed component.
Capacity and licensing also matter. A standby network may be able to carry essential apps but not the entire production workload. We record the resources required during activation and the constraints that could delay them, including provider actions and cloud permissions that must be available at the time of the incident.
Build activation and reversal procedures
The network runbook identifies the exact decision points, owners and verification steps needed to activate recovery network access. It includes route changes, security policy, public addressing and any coordination with external providers. Tasks are ordered to avoid advertising a recovered service before it is actually ready to accept traffic.
Returning to normal operation receives its own plan. Failback can create route asymmetry, stale DNS responses or duplicate reachability if it is treated as a simple reversal of one command. We find the checks needed to confirm that app and network state are aligned before withdrawing the recovery path.
Exercise the plan with representative tests
A controlled exercise checks the network path from relevant users and partner positions to the recovery workload. We test DNS, permitted access and important infrastructure dependencies, with app owners confirming the business workflow. A successful ping to the recovery subnet is not evidence that the service is usable.
The exercise records timings, failures, manual dependencies and limitations. Where a full disaster scenario cannot be reproduced safely, we state which parts were tested independently and which remain assumptions. Findings are assigned owners and retested after correction rather than left as notes in a report that will not be used until the next incident.
Keep recovery aligned with production change
New subnets, certificates, security rules and app endpoints can make a recovery design obsolete. We connect network recovery records with the customer's change process and recommend a review when relevant dependencies change. Monitoring should identify unavailable standby paths before a production incident requires them.
MCI can provide the network workstream within a wider recovery programme or assess a current hybrid cloud routing design. Share the app recovery plan and target setups so we can identify the network access, policy and coordination needed. The outcome is tested network evidence and usable procedures, not an unsupported claim that network access alone makes the business disaster-ready.
