Decide who is responsible for the first response
Someone needs authority to investigate, communicate and coordinate recovery. If ownership changes by time of day, document the handoff instead of assuming the right person will notice an alert.
Know the critical user journeys
Define the actions that prove the service is actually working: login, data writes, checkout or billing, background processing and key integrations. Server uptime alone does not prove the product is healthy.
Keep recovery access independent
Make sure the team can still reach hosting, DNS, backups and status information during an account or identity-provider problem. Recovery credentials that depend on the failed system can turn a small incident into a lockout.
Preserve useful evidence
Retain application and system logs long enough to understand what happened. Record deployment times and major configuration changes so the team can correlate a failure with recent work.
Make rollback a normal option
A release procedure should include a quick way to decide whether to roll back. Database changes need extra care because application code can often be reverted faster than modified data.
Write the first customer update template now
A short factual update should state what users are experiencing, what the team is doing and when another update will be posted. Avoid inventing a root cause before it is known.
