[Zope] stability of zope?

[Meilicke, Scott]

I think it is counting uptime and downtime in terms of seconds(or some sort
of time measurement).  So if the total time the server has been running is
100 hours, and it was down for 3 one hour periods, then uptime would be
reported as 4 days, 1 hour (97 hours total).  Downtime would be 3 hours.  I
agree, there were 1-3 days where services were interrupted in this example.
So this uptime stat I ran does consider a reboot downtime, but measures time
more granularly than days.

This box is an Intranet server, so netcraft is not appropriate.  You can
assume however, that the uptime is no better than these stats, as this is
the OS, and the service may have had difficulties of its own, including
planned downtime (restarting zope for product installs, bad python programs
gone bad, etc.)

If you have 32 reboots in 596 days, then the uptime is not 596 days. The 
line "Mean Time Between Reboots" states, that the average uptime is 18.65 
days. So this stat doesn't think that a reboot is downtime. What says 
www.netcraft.com about your uptime?
