What Is the Follow-the-Sun Model?
The follow-the-sun (FTS) model is an operational strategy where work is handed off between geographically distributed teams so that each team works during their normal business hours while collectively providing around-the-clock coverage. No team works nights — the "sun" of productivity literally follows the Earth's rotation.
Classic Three-Region Setup
The most common FTS implementation uses three regional hubs roughly 8 hours apart:
- Americas hub (e.g., Austin, Toronto, São Paulo): Covers UTC-8 to UTC-3 (business hours)
- EMEA hub (e.g., London, Dublin, Amsterdam): Covers UTC+0 to UTC+3
- APAC hub (e.g., Sydney, Singapore, Seoul, Tokyo): Covers UTC+8 to UTC+11
Each hub works an 8-hour shift and hands off to the next hub at the end of their day. Together, they cover 24 hours without any single team working overnight.
The Handoff Process
The quality of a follow-the-sun operation depends almost entirely on the quality of handoffs. A poor handoff loses context, duplicates work, or leaves customers waiting. A good handoff process includes:
- End-of-shift summary: What was worked on, what is pending, what is escalated
- Live ticket/case handoff: Open cases transferred with full context notes
- Brief overlap window: 15–30 minutes where outgoing and incoming teams overlap for questions
- Shared knowledge base: Runbooks, FAQs, and escalation paths accessible to all hubs
Tools for Follow-the-Sun Operations
- Zendesk / Freshdesk / Intercom: Ticket routing and assignment by region/time
- PagerDuty / Opsgenie: Incident escalation across time zones with on-call schedules
- Confluence / Notion: Shared runbooks and decision trees accessible globally
- Slack cross-region channels: Dedicated handoff channel with end-of-shift posts
Common Follow-the-Sun Pitfalls
- Insufficient overlap: Teams need at least 30 minutes of concurrent time to transfer context effectively.
- Missing runbooks: If a APAC engineer has to handle an EMEA-specific issue, they need documentation to do it correctly.
- Unequal ticket quality: Don't pass difficult tickets to the next shift without full context — this degrades trust between hubs.
- Holiday gaps: When one hub is on holiday, the other hubs need to know and adjust coverage expectations.
Is Follow-the-Sun Right for Your Team?
FTS works well for customer support, DevOps, and incident response teams. It requires consistent process discipline and significant documentation investment. For smaller teams with fewer than 5–6 people per region, a lighter async-first model with defined SLAs may be more practical.
