Network Diagnostics

This overview shows which network diagnostic tools — MTR reports and speed tests with wget and iperf3 — help you find the cause of slow connections, high latency or packet loss on your server.

Available Diagnostic Tools

Different tools are suited for different types of problems. The guides below walk you through each one step by step.

Which Tool Should I Use?

The right tool depends on the type of problem you are experiencing:

→
Packet loss or high latency — Create an MTR report and submit it to our support team.
→
Slow transfer speeds — Run a speed test to measure your actual available bandwidth.
→
Unclear cause — Run both tests and share the results with our support team.
