About Looking Glass
Our Looking Glass lets you run network tests from our infrastructure. Use ping to check basic connectivity, or MTR for a hop-by-hop view with packet loss statistics.
Frequently asked questions
What is the AS202520 Looking Glass?
It is a public diagnostic tool. It lets you run network tests directly from our infrastructure toward any IP address or host. You can see how the AS202520 network reaches your resource and what the packet path looks like from our point of view.
Which tests are available?
Ping answers whether a host responds at all and with what latency. MTR walks the path hop by hop and shows you which hop is dropping packets. IPv6 variants appear in the list only when the node you picked has an IPv6 route.
From which locations are tests run?
Tests run from nodes in the AS202520 network. You pick the source from the list above the form, which holds the nodes answering at that moment. The list can therefore be shorter than our network presence.
Why does the Cloudflare Turnstile check appear?
Turnstile is a lightweight check that distinguishes humans from bots without annoying puzzles. It protects the tool from automated abuse and overload, so the Looking Glass stays fast and available for everyone.
When should I use ping versus MTR?
Ping is best for a quick answer to whether a host responds and what the basic latency is. Choose MTR when you want to pinpoint a problem along the path. It merges traceroute with continuous measurement and shows packet loss and latency at every hop.
