Lambda prod alias promotion — v40 deploy
🕐 Next sprint · Low-traffic window · ~15 min
LAMBDAPROD ALIASZERO-DOWNTIME
Promote Lambda prod alias to v40 after feature batch. Includes alias parity check and rollback readiness verification. Zero-downtime via alias promotion.
Impact Assessment
~5–15s of potential cold-start latency during first invocation on new alias. No user-facing downtime expected. API Gateway routes continue serving via existing alias during swap.
UPCOMING

Submit AWS SES production access request. Fill out use-case description, sending practices, and suppression list configuration. AWS review may take 1–3 business days.
