<b>Q: Why monitor from multiple regions if my server is in one place?</b>

<b>Q: Why monitor from multiple regions if my server is in one place?</b>

A: Because your users aren't in one place, and the failures between them and your server are invisible from a single vantage point. A route from a US node can be clean while European visitors hit a broken peering link, a regional CDN node, or a GeoDNS rule pointing them at a dead edge.

Single-region monitoring also can't tell a real outage from a problem on the monitor's own path. Multi-region gives you a vote: if 1 of 5 regions fails, it's probably the network; if 5 of 5 fail, it's your server.

Pick regions that mirror your actual traffic, not a random spread. If 80% of your audience is North America and Western Europe, monitor heavily there and add one distant node as a tripwire.
