Alarms look good, but the thresholds might need some tweaking based on what we see in behaviour.

Worth adding a check/alarm/canary for some other things too, like inability to hit the OAuth service (early on-prem outage warning) or for outages to any BCGW connections. This could also be added to the API healthcheck (not the readiness check for instance spin down!) for ease of checking with a simple response package. Could use a lambda
