Critical maintenance clause: Copy, customize, and use instantly
Introduction
A critical maintenance clause outlines how and when essential system maintenance or updates may be performed, especially in situations that require urgent action to prevent service disruption, protect data integrity, or ensure security. It helps set expectations around notice periods, service suspension, and responsibilities during such maintenance.
Below are templates for critical maintenance clauses tailored to different scenarios. Copy, customize, and insert them into your agreement.
