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.

Other checks in news & media: Cookpad status check, Yahoo Japan status check, Asahi Shimbun status check. Compare results separately; these links do not establish a shared outage.

Where to report problems with Niconico

Details to include in your report

Video or broadcast ID, playback/comment step, app/browser and time; keep account details private.

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

Check for a different cause. 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.
Keep useful report details. Video or broadcast ID, playback/comment step, app/browser and time; keep account details private.
