On-Call and Distributed Teams: Follow-the-Sun Done Right
Follow-the-sun is the gold standard for distributed teams. The conditions that make it work are concrete; the failure modes are predictable.
Why follow-the-sun
Each region covers their own daytime; nights belong to next region.
No human paged outside daytime; the program is sustainable indefinitely.
Four conditions
- 1. Three regions geographically distributed.
- 2. 4-6 engineers per region.
- 3. Strong handoff doc + rotation system.
- 4. Aligned tooling across regions.
Common pitfalls
Two-region setup: gaps; doesn’t work for 24-hour coverage.
One distributed team without regional handoff: everyone always on call.
Tool fragmentation: each region uses own tools; no cross-region visibility.
Bridging artifact
Handoff doc updated at end of each region’s shift; reviewed at start of next region’s shift.
The doc is the institutional memory across regions.
Antipatterns
- Two regions only. Coverage gap.
- One global team without regional ownership. Always-on misery.
- Different tools per region. Fragmentation.
What to do this week
Three moves. (1) Apply this practice to your next on-call rotation. (2) Survey the team after one cycle. (3) Iterate based on feedback; the discipline is the cadence.
