[atlas] New on RIPE Labs: RIPE Atlas Measurements with Tagged Probes coming soon

When you schedule a measurement, the system tries to find the best probes
that match your criteria and involve them in your measurement. For now, this
set of probes does not change over time automatically -- but you can ask for
changes yourself.

We have a feature on our roadmap to deal with situations where probes
disappear over time, and do "something" about it: warn the user, replace
with new probes, stop the measurement, ... The issue is that this, by
definition, results in a change of probes over time, so interpreting the
results becomes trickier.

At the moment this feature is only planned to work with probes that
disappear (ie. get unplugged), not when they change properties. That is even
more difficult to do -- think about how to avoid flapping, for example.

It would be useful to hear what other think about such features, so we can
better understand what the user needs are.

Robert
