International On-Call

Cross-border rotation.

Follow-the-sun benefits

24/7 coverage without nights. Engineers on-call during their own business hours.

Faster response for distributed customers. Users in any region hit on-call within their daytime.

Reduced burnout. No 3 AM pages for any single engineer.

Engineers in 3-4 time zones for full coverage. Asia, Europe, Americas at minimum.

Cross-team coordination. Handoff at zone transitions. Tools must support across regions.

Cultural and language considerations. Engineers in different regions may approach incident response differently; align practices.

Synchronous handoff at zone transitions. 15-30 min overlap; outgoing briefs incoming.

Active incident transfer: explicit transfer of incident commander role.

Documentation in shared tools. Incoming engineer reads scrollback; outgoing confirms handoff acknowledged.

Standardise tools across regions. Slack, PagerDuty, dashboards used by all.

Per-region holiday calendars. Coverage adjusts for regional public holidays.

Annual review of zone coverage. Hiring patterns and regional growth shift balance over time.
