#
# PURPOSE
# ─────────────────────────────────────────────────────────────────────────────
# The weekly read of what Tools/uptime_probe.sh has been recording every minute: anything down
# right now, and anything that was not perfect over the last seven days. Runs in the Sunday
# Morning Coffee Report.
#
# Silent on a clean week. A report that always says something is a report nobody reads, so this
# prints nothing and notifies nothing when every domain was 100%.
#
# ==============================================================================================
# OPERATIONAL MODEL
# ==============================================================================================
#
# uptime_probe.php --report exits 1 when it has something to say and 0 when it does not, so the
# decision to notify is the exit code rather than this script parsing the text it just printed.
#
# ==============================================================================================
# CONFIGURATION
# ==============================================================================================
#
# UPTIME_PROBE_ENABLED   nothing here runs when the probe is switched off
#
# ==============================================================================================
