Latency
Measure round-trip time from important user and office networks, not only from a cloud test node.
Network
Measure the route that matters to your users.
Network marketing numbers are not enough. Test latency and transfer performance from the actual regions and ISPs that matter to your application.
Quick answer
For network-sensitive workloads, test from representative client networks to the actual VPS network. Measure latency, packet loss, route stability and real transfer performance. A single headline bandwidth number does not describe every path on the Internet.
Testing
What to measure
Packet loss
Persistent loss can harm interactive applications even when nominal bandwidth looks high.
Route
Traceroute or MTR can help identify where a path changes, but interpret results carefully because some hops deprioritise probes.
Real transfer
Use application-relevant transfers and several locations. One speed test should not be treated as universal performance.
Transparency
Looking Glass endpoints are published only when they are real
This package intentionally does not invent test IPs or benchmark URLs. Add production test endpoints in config.php once you have confirmed which SERVER1 network resources are intended for public testing.
Test IP
Publish an address designed for public diagnostics, not a customer or management interface.
Test file
Use a controlled public test object and monitor abuse or unexpected transfer cost.
Looking Glass
Expose only safe diagnostic functions and rate-limit them appropriately.
FAQ
Questions people ask before ordering
A port speed is only one constraint. Internet performance also depends on congestion, peering/transit, remote networks, route choice, protocol behaviour and the application itself.
Publish or provide a test endpoint only when SERVER1 has designated one for public diagnostics. This site intentionally does not fabricate a placeholder address.
Choose by workload, not by guesswork.
If you know the resources you need, open the live catalogue. If not, send the workload and we will help narrow the choice.
