Qué significa
NTT 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
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 NTT down right now?
Outages typically come from CDN/DNS issues, failed deploys, regional routing problems, or DDoS. We can't see NTT's internal cause — we only confirm reachability from each monitoring region. If all 4 regions failed, it's a confirmed outage on NTT's side. If only some failed, the impact is regional.
Is NTT 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 NTT's side.
How often does isitdown.io re-check NTT?
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.
Status badge
Embed a live status badge on your site, README, or status page. Updates automatically — same status-aware SVG the rest of isitdown.io uses.
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.
