About the Network Tools

A set of network diagnostics that run from our servers so you can test a host from outside your own connection — useful when you need to know whether a problem is yours or theirs.

• Tests run from our server, not your browser
• Covers DNS, email deliverability, HTTP and TLS
• No account required

Frequently asked questions

Why test from a server instead of my machine?

Testing from outside your network rules out your own DNS cache, firewall or ISP, which is exactly what you need when a site works for you but not for someone else.

Do I need an account?

No. There are reasonable rate limits to keep them available for everyone.
