Immediate actions
1. Confirm you are the payments primary, or page that primary before changing traffic. 2. On the payments-api golden dashboard, confirm the authorization error rate has stayed above 2% for five minutes. 3. Turn on rollback flag harbor-rollback-77. New authorizations move to the last known-good processor path. 4. If the error rate is still climbing after ten minutes, drain canary cell pay-api-cell-3 and leave cells 1 and 2 serving.
Escalate
Page the payments engineering manager if harbor-rollback-77 has not brought the error rate under 0.5% within fifteen minutes.
