Regions & latency

Choose PoPs and interpret latency budgets.

Pick regions based on where your users and origins live. Multi-region deployments reduce p99 latency but increase cold inventory and configuration complexity.

Available regions

CodeLocationTypical p50 RTT
us-eastAshburn12 ms
us-westOregon15 ms
eu-westFrankfurt14 ms
ap-southSingapore18 ms
ΔL≈∣Luser−Lorigin∣+Lreplication\Delta L \approx |L_{user} - L_{origin}| + L_{replication}
Tip
Pin stateful workloads to one region. Use multi-region only for stateless handlers or with an explicit consistency model.
