Frequently asked questions
What does ping measure?
Ping measures round-trip time (RTT) — how long it takes for a packet to travel from our server to the target host and back. Lower is better; anything under 50ms is excellent for most use cases.
What is packet loss?
Packet loss occurs when ICMP packets sent to the host don't receive a reply. Even 1–5% loss can cause noticeable lag in real-time applications. 0% is ideal.
Why might ping fail?
The target host may block ICMP packets (common on firewalls and cloud servers), the host may be offline, or DNS resolution may have failed.
