A public window into the GeiseIT network: run real diagnostics from our infrastructure and see how it reaches the rest of the Internet.
A Looking Glass is a public tool that lets anyone run network diagnostics from the point of view of a network operator. Instead of testing from your own connection, you ask GeiseIT's network to reach a destination and report what it sees.
That makes it useful for checking whether a service is reachable from somewhere else, comparing IPv4 and IPv6 paths, and understanding where a slow or broken route goes wrong.
Transparency builds trust. Publishing how our network performs is a straightforward way to show customers and peers what they can expect, and to help anyone troubleshoot connectivity to and from GeiseIT.
It is also a real production workload that we run on our own Kubernetes platform. See how it is built.
Read-only BGP views (routes, prefix and ASN lookups, session status) appear once a BGP data source is enabled for this Looking Glass.
When you run a test, the request goes to our API, which validates the destination and hands it to an isolated diagnostics service. That service runs standard network tools with fixed arguments and strict time and output limits, then returns structured results.
Every result has a Summary for quick reading and a Technical view with the raw output. If a result ever comes from simulated data, it is clearly labelled.
We don't ask you to sign in and we don't set tracking cookies. The only thing stored in your browser is your theme preference.
To operate and protect the service we process your IP address for rate limiting and keep short-lived operational logs. Recent activity shown on the dashboard is anonymous, and internal network addresses on a route are hidden and shown as “Internal network”.
Curious how it runs?
This Looking Glass is a Kubernetes-native workload on GeiseIT-owned hardware.
