an \emph{outage reporting system} that sifts through this data
to find the most \emph{interesting} events.
We explore multiple metrics to evaluate
``interesting'', reflecting the size and severity of outages.  We show
that defining interest as the product of size by severity works well,
avoiding degenerate cases like complete outages affecting a few
people, and apparently large outages that affect only a small fraction
of people in an area.  We have integrated outage reporting into our
existing public website (\url{https://outage.ant.isi.edu}) with the
goal of making near-real-time outage information accessible to the
general public.  Such data can help answer questions like ``what are
the most significant outages today?'', ``did Flordia have major
problems in an ongoing hurricane?'', and ``are there power outages in
Venezuela?''.",
