Check if bitFlyer is down, official outages, user-reported issues, and outages map.
bitFlyer is working normally
Check the number of user-reported issues over the past 24 hours, grouped into 20-minute intervals. It's normal to see occasional reports, which may be due to individual user issues rather than a broader problem. We only consider an issue widespread if there are multiple reports within a short timeframe.
IsDown has tracked 28 incidents since started monitoring bitFlyer status in January 2023. We collect data from 4522+ services, and normalize the data to give you a clear picture of the impact of the outage. It will show official bitFlyer outages and also issues that we're started by a spike in crowdsource reports.

IsDown and DownDetector help users determine if bitFlyer is having problems. The big difference is that IsDown is a status page aggregator. IsDown monitors a service's official status page to give our customers a more reliable source of information instead of just relying on reports from users. The integration allows us to provide more details about bitFlyer's Outages, like incident title, description, updates, and the parts of the affected service. Additionally, users can create internal status pages and set up notifications for all their third-party services.
