Response time by location, last 24 hours
| Location | Average response | Reached |
|---|---|---|
| Berlin 1, Germany | 226 ms | 1 of 1 checks |
| Falkenstein, Germany | 215 ms | 1 of 1 checks |
| Berlin 2, Germany | 220 ms | 1 of 1 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.

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 d3js.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.
