Server downtime indicates a period when an online business's services are unavailable due to system failures, maintenance, or other issues. This can severely impact revenue, customer trust, and operational efficiency, as users cannot access necessary services. Prolonged downtime can lead to lost sales opportunities, frustrated customers, and damage to the company's reputation. It's crucial for businesses to have strategies in place to minimize downtime, such as regular maintenance, redundancy systems, and effective monitoring tools to quickly detect issues and resolve them efficiently to ensure continuous service availability.
