Indeed. There are two things here:

1) We want to re-activate probes that are down due to local problems, e.g. problems
that the host can do something about. This is in the interest of the whole community
because it helps to keep a large measurement network up and operating. For this purose 
we are already sending out e-mails after a couple of days of downtime. This is not
going to change and we are considering more 'agressive' poking if the e-mails do not
bring the probe back up.

2) Providing a service to the hosts that warns them of downtime etc. This should be
configurable of course in terms of who gets alerted and how sensitive the trigger for an
alert is; the default shold be "off". I have the feeling that this is also someting we 
may want to address as part of a more general alerting mechanism. As a host I might be 
interested in monitoring a totally different target, my family server located at a hoster,
and do it not only from my own probe. That is called user defined measurements and
an alerting system based on that will cover the case we are discussing now, because one
will be able to monitor the first upstream from one's own probe.

Right?
