<p style="margin: 1.2em 0px ! important;">In the context of your
research, you could view “failed” and “no suitable probes” as
finished, but here is a complete list of possible measurement
statuses:</p>
<ul style="margin: 1.2em 0px;padding-left: 2em;">
<li style="margin: 0.5em 0px;"><strong>Specified</strong>: the
measurement has been defined and sent to our infrastructure to
be relayed to the probes.</li>
<li style="margin: 0.5em 0px;"><strong>Scheduled</strong>: The
measurement has been relayed to the probes. If the start time
is immediate, this status doesn’t last very long.</li>
<li style="margin: 0.5em 0px;"><strong>Ongoing</strong>: The
measurement is running on available probes.</li>
<li style="margin: 0.5em 0px;"><strong>Stopped</strong>: The
measurement was stopped either on schedule, by the user
requesting an early stop.</li>
<li style="margin: 0.5em 0px;"><strong>Forced to Stop</strong>:
The measurement was killed prematurely due to a lack of
available credits.</li>
<li style="margin: 0.5em 0px;"><strong>No suitable probes</strong>:
The measurement cannot currently be executed as defined due to
a lack of available probes. This may be because you asked to
use probes that don’t exist (for example, probes in an AS in
which there are no probes) or because all of the probes you
requested were too busy to take on new jobs. This latter
scenario is very rare however.</li>
<li style="margin: 0.5em 0px;"><strong>Failed</strong>: If a
probe never actually runs a single measurement over the
duration of the specified start/stop time (typically due to a
lack of available probes), it will be marked as <code style="font-family: Consolas,Inconsolata,Courier,monospace;margin: 0px 0.15em; padding: 0px 0.3em; white-space: pre-wrap; border: 1px solid rgb(234, 234, 234); background-color: rgb(248, 248, 248); border-radius: 3px; display: inline;">Failed</code>
once the stop time has been reached.</li>
</ul>
<p style="margin: 1.2em 0px ! important;">In other words, <code style="font-family: Consolas,Inconsolata,Courier,monospace;margin: 0px 0.15em; padding: 0px 0.3em; white-space: pre-wrap; border: 1px solid rgb(234, 234, 234); background-color: rgb(248, 248, 248); border-radius: 3px; display: inline;">Specified</code>,

are statuses potentially assigned to running measurements (or at
least those who may return results at some point), while <code style="font-family: Consolas,Inconsolata,Courier,monospace;margin: 0px 0.15em; padding: 0px 0.3em; white-space: pre-wrap; border: 1px solid rgb(234, 234, 234); background-color: rgb(248, 248, 248); border-radius: 3px; display: inline;">Stopped</code>,

and <code style="font-family: Consolas,Inconsolata,Courier,monospace;margin: 0px 0.15em; padding: 0px 0.3em; white-space: pre-wrap; border: 1px solid rgb(234, 234, 234); background-color: rgb(248, 248, 248); border-radius: 3px; display: inline;">Failed</code>
are statuses assigned to measurements that will not be returning
any more results.</p>
