Caveats and Possible Discrepancies

• Scheduled Maintenance and Upgrades - These statistics do not account for scheduled maintenance outages. Every host needs to do maintenance to keep their fleet up to date, secure and running smoothly. Although we do this work during off-peak hours (at night), it still counts as "downtime" in the eyes of this monitoring service.
• Webserver-only Monitoring - Only the webserver (Apache, port 80) is monitored. If the webserver is down but other services (Email, FTP, MySQL) are up, the entire server reports down.
• Sampling Error - The reported uptime may vary slightly from the server's actual uptime, as the monitoring interval is set at 1 minute.  For instance, if a server goes down right before a service check, and then we reboot it and it's back online within 30 seconds, the monitor will catch it on the next check (which is in 1 minute) and estimate a 1 minute downtime when in reality there was only 30 seconds of downtime.
• Calculations - These percentages are calculated based upon the entire reporting period; not just the timeframe that has passed. We're always looking at the full month or year as opposed to the month-to-date or year-to-date amounts.
