9. Implement and test HA, link redundancy, alternate routes, and failover mechanisms for critical services; participate in DR/BCP exercises, validating secure connectivity to critical services in OCI and AWS.
10. Manage carriers/ISPs, OEMs (incl. Fortinet), and MSPs: contracts, SLAs, escalations, billing, and reconciliations; support RFP/RFQ evaluations and recommend cost‑effective modernizations and optimizations.
