Qué significa
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.
Qué hacer ahora
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.

Other chains
Metodología
- Sonda
- We send a GET request to the target URL from each region and time the full response.
- Se considera CAÍDO si
- Every region fails the request (connect refused, DNS error, timeout, or HTTP 5xx).
- Se considera DEGRADADO si
- At least one region succeeds but at least one fails — the outage is partial or regional.
- Detalle
- 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.
- Cadencia
- Every 5 minutes, in parallel across 4 monitoring regions (US East Virginia, US West Oregon, Europe London, Asia Singapore).
- Objetivos con límite de tasa
- 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.
- Fuente de datos
- 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.
