Based on 1 day of checks so far. Checks that failed because of how we test, not because of the site, are left out.
Response time per hour, last 24 hours
Response time by location, last 24 hours
| Location | Average response | Reached |
|---|---|---|
| Falkenstein, Germany | 554 ms | 2 of 2 checks |
| Berlin 2, Germany | 535 ms | 3 of 3 checks |
Each check runs from all locations at once. A location far from the site’s servers answers later; that says nothing about the site being slow.
Outage history
No confirmed outage on record. An outage is listed once GNU Radio could not be reached from at least two locations in two checks in a row.

About GNU Radio
GNU Radio - Free & Open Source Software Radio
GNU Radio is a free and open source software development toolkit for building software radios and signal processing systems. Run it on your desktop, or try GNU Radio flowgraphs in your browser with GNU Radio World.

We can reach it, but you cannot?
- Reload the page without the cache: Ctrl + F5 on Windows, Cmd + Shift + R on a Mac.
- Open the site in a private window. If it works there, clear the cookies and cache for gnuradio.org.
- Try another network, such as mobile data. If that works, the problem is with your provider or router.
- Switch to a public DNS resolver such as 1.1.1.1 or 8.8.8.8, then flush your DNS cache.
- Turn off VPNs, proxies and ad blockers for a moment. Some sites refuse those connections.
