Is Roblox down? (client-side check)

This page runs a network probe from your browser against four Roblox endpoints and reports whether each one responds. It's not an official status feed — it tells you what your network can reach right now.

What this page actually measures

A truly authoritative Roblox status page lives at status.roblox.com — that's the company's own incident feed, and it's what to check first during a confirmed outage. What this page does is independent: from your browser, it tries to reach a few Roblox endpoints and reports whether the request completed. If your home network has a DNS issue or a parental-control filter blocking Roblox, this page will show those endpoints as unreachable even though Roblox itself is fine.

The probes use a mix of techniques:

  • Thumbnail / CDN endpoints are probed with <img> tags. An image either loads (success) or errors (failure). This is the most reliable signal because image requests aren't subject to CORS.
  • roblox.com and API edges are probed with fetch(url, { mode: "no-cors" }). The response is opaque — we can't read it — but we can tell if the request reached a server.
  • Results are cached in sessionStorage for 60 seconds so a refresh doesn't hammer the endpoints.

When to trust this page

Use it as a first-pass check. If three of the four probes fail, something is almost certainly wrong on Roblox's side (or your whole internet is down — try opening any other site). If only one probe fails, it's more likely a regional CDN node, a DNS hiccup, or your local network filter.

If the page reports everything green but you still can't connect in the Roblox app, the issue is probably with the Roblox client itself, the specific server you tried to join, or login services — none of which this page can detect.

FAQ

Why can't this tell me what's wrong, just whether something is wrong?

BloxToolbox is a static site. It has no backend, so it can't query Roblox's internal incident feed. We measure reachability and let you draw the conclusion.

Will this page get me unbanned if I'm rate-limited?

No. This is a reachability test, not an account-status check.
