Understanding Niconico connection and service problems
Niconico's nicovideo.jp homepage links its own general help and separates recorded videos from live broadcasting and other entertainment services. Video playback and the comment layer can behave differently.
The checker above requests nicovideo.jp from eight configured locations and shows the responses and measurement times. Compare those observations with the actual Niconico action that failed. A homepage response alone cannot verify an account, app workflow or transaction.
For separate news & media services, compare these individual checks: Cookpad status check, NDTV status check, Daum status check. Compare results separately; these links do not establish a shared outage.

Where to report problems with Niconico
Open Niconico help / reporting. Use the contact, technical-help or account route described there. Sign-in, support entitlement and available channels can vary; a public community discussion is not a private support ticket.
Details to include in your report
Video or broadcast ID, playback/comment step, app/browser and time; keep account details private.
Attach the checker’s downloaded JSON if it helps show the hostname, regional responses and original timestamps. Describe what happened in your browser or app as well. A report sent to WebsiteDown.org is not automatically forwarded to Niconico.
What to check when Niconico is not working
These are troubleshooting comparisons, not claims that Niconico is currently experiencing a particular incident.
Start with the action that failed
Compare the exact video with another recording and note whether the player fails or only comments fail to appear.
Narrow down the affected service
For a live-broadcast problem, identify that service explicitly. Preserve the content identifier and use Niconico's general help rather than Dwango's advertising or press-contact routes.
Read the actual checker response
A 403 Forbidden or 429 Too Many Requests means the host answered but refused or limited that request. A timeout gives no HTTP response. Keep those outcomes separate and check the available-region count before treating the result as broad evidence.
How to check if Niconico is down
- Identify video or live broadcast.
- Compare another recording.
- Check the comment layer.
- Open Niconico help.
Use the comparison and support guidance above for the specific action. Keep the original check and error timestamps together; a cached result can be older than the problem you are seeing.
A useful comparison for Niconico
Repeat the same action in a second browser or on another available connection, keeping the item and account the same. Change one thing at a time so the result is comparable. Leave required workplace or school security controls in place.
Follow the website troubleshooting guide for connection checks. Preserve any unsent work before refreshing a form or changing a session.
