We offer 99.9% SLA with our customers for our shared hosting service. Higher SLA options are available for dedicated hosting options. Maintenance is performed during off peak hours on weekends. For a major upgrade, downtime is normally not more than 10-15 minutes. For minor upgrades, there is 0-5 minutes downtime. Enhanced, tailored SLA are available when using customer’s Microsoft Azure Cloud or VIDIZMO’s dedicated cloud.
