The problem
A single check location tells you how your app performs from one place — not from the cities your actual users are connecting from. Latency problems elsewhere in the world can go unnoticed for a long time.
Set up in three steps
Add a global monitor
Point it at the endpoint you want to check from multiple probe locations.
Pick your probe locations
Use the recommended global set, or choose the specific locations that matter for your users — up to 25 on Business.
See per-location results
Track latency and status by location, with a sane fallback if any one probe location is temporarily unavailable.
What Holter does
Run response-time checks from a set of global probe locations on an hourly sweep and see per-location latency and status. Your primary uptime monitor keeps driving incidents and alerts; the global sweep adds the geographic picture. Use Holter's recommended set or pick the specific locations your users care about.
- ✓ Pro: a smaller recommended probe-location set
