The monitoring system has been broken for a long time and can not be
taken seriously. I joined the pool recently and score is all over the
place, with regular emails telling me the server cannot be reached,
while at the same time, getting hundreds of a hits a minute in some
cases and a server uptime of months with no break.
There is also a prototype monitor site with < 1 monitor system, but
that produces even weirder results, from tests done here.
