We request ntt.com and note whether it answers. These automated checks do not sign in or use the app's features.
Available evidence
We check whether its website loads every 5 minutes. This does not test sign-in, payments, calls or every feature of its app or network. We show a website problem when a quarter of the eligible places cannot load it, and an outage when half cannot. Places that normally cannot reach it are excluded. With too few results, we say we cannot tell.
Recent problems
No problems recorded since 4 Nov 2026.
Alert me when NTT is down
HonkWatch can load NTT's website for you from several cities and alert you by email, Slack, Discord or Telegram when it stops answering.

Questions
Is NTT down, or is it just me?
Our checks reach NTT's website from most of our cities. This does not rule out problems with sign-in, payments, an app or a local network. Check the community reports above and report your experience.
How do we know?
No official status feed is connected for NTT. We load ntt.com from our probes and note whether it answers. People can report problems here. Their reports appear separately and may reveal issues before a provider update.
How often do we check?
The website every 5 minutes, day and night. We keep 90 days of available check history: a day we have no reading for shows as "no data yet", never as working.
