Each uptime calculation is measured by the uptime for the entire customer base across all hosting systems for Network Solutions. Scheduled maintenance to Network Solutions systems is excluded from the calculation of the uptime for UNIX and Windows users as well as events causing downtime that are outside of the control of Network Solutions or are caused by third parties.
