Protect the continuity of your Infoblox grid environment with 5 years of Level 3+ maintenance coverage tied to an upgrade path on IB-2000-A. This service is designed for infrastructure teams managing long-lived DNS and grid deployments where support depth matters as much as coverage duration. Level 3+ maintenance is aimed at complex operational conditions that require more than standard assistance. It gives your team a vendor-backed path for escalation while you maintain service stability through a planned upgrade or lifecycle transition. For enterprise environments, that matters because grid services often sit at the center of authentication, application routing, and core network dependencies. A 5-year term supports organizations that plan in multi-year cycles and want to avoid gaps in maintenance during refresh, expansion, or modernization programs. Instead of treating support as a short-term transaction, this offering anchors the environment to a longer coverage window, helping reduce risk and preserve operational control across the full upgrade horizon.
