Once a server is setup and running smoothly only minor updates have to be made. The only noticable downtime would be a service restart or reboot and many time this can be done fast enough the monitoring service will not detect it. I am surprised this qualified as a NEWSWORTHY FOR W3REPORTS. If 10 months of 100% stats is worth of a press release maybe we should put out one as well.
