Que signifie ce résultat

Arbitrum One is reachable from all 4 monitoring regions.

If you still can't connect, the outage is on your side: DNS cache, VPN routing, ISP filtering, or a browser-level block. Try a different network or device to confirm.

Que faire ensuite

Check your DNS

Flush your DNS cache: ipconfig /flushdns on Windows, sudo dscacheutil -flushcache on macOS.

Try another network

Switch between Wi-Fi and mobile data, or disable your VPN. If it works there, the issue is on your primary network.

Browser reset

Try an incognito window or a different browser — a bad extension or cached error page can masquerade as downtime.

FAQ

Why is Arbitrum One down right now?
Outages typically come from CDN/DNS issues, failed deploys, regional routing problems, or DDoS. We can't see Arbitrum One's internal cause — we only confirm reachability from each monitoring region. If all 4 regions failed, it's a confirmed outage on Arbitrum One's side. If only some failed, the impact is regional.
Is Arbitrum One down for everyone or just me?
Look at the per-region grid above. If every region succeeded, the issue is local to your network — flush DNS, switch networks, or disable your VPN. If two or more regions failed, the outage is on Arbitrum One's side.
How often does isitdown.io re-check Arbitrum One?
Every 5 minutes via background HTTP probes from US East, US West, Europe, and Asia. You can also re-run on demand by reloading — the verdict above reflects the latest probe.

Méthodologie

Sonde
We send a GET request to the target URL from each region and time the full response.
Compté comme EN PANNE si
Every region fails the request (connect refused, DNS error, timeout, or HTTP 5xx).
Compté comme DÉGRADÉ si
At least one region succeeds but at least one fails — the outage is partial or regional.
Détail
Per-region results include HTTP status code, response time, and best-effort DNS / connect / TLS / first-byte phase timings when the Node HTTP client exposes them.
Cadence
Every 5 minutes, in parallel across 4 monitoring regions (US East Virginia, US West Oregon, Europe London, Asia Singapore).
Cibles limitées en débit
If a host returns 429 or consistently drops connections from our IPs, we cap retries at 3 and report the last observed status — we do not flood the target to confirm the outage.
Source des données
Direct probes from our monitoring infrastructure. We do not aggregate crowd reports, Twitter mentions, or DownDetector signals — every result on this page is a live network request.
