This ping measures the technical health of the background update system.
Said system downloads and processes updates when Firefox is not running. It
is expected that this ping will be analyzed by humans to gain confidence in
the implementation as the staged rollout of the system proceeds to the
release channel, before settling into an automated analysis to detect spikes
in background update failure rates. This ping will also help to
characterize the update-related settings of our user population.
Right now the background update system, and therefore this ping, is
restricted to Windows.
This ping is submitted only by the background update task. It should be
submitted once per background update task invocation. The expected schedule
is every 7 hours, controlled by the pref `app.update.background.interval`,
and subject to scheduling decisions made by the OS.
The ping was sent as part of the normal background update task execution.
