Upbit API status

Over the 60 days of a 90-day window up24 has measured so far, Upbit's REST API answered 99.99% of 3,002,372 checks, with a typical p95 of 314ms and a typical p50 of 265ms. Its worst day was 02 SEP 2026, at 99.64%. up24 opened 35 incidents against it in that window — uptime counts REST checks only, and an incident is as often a WebSocket feed that stalled or a socket that dropped. Is Upbit down right now? →

Latency is measured from each region separately and never averaged between them — the distance is the measurement. Uptime, incidents and the 90-day bars above are the opposite: they combine every region by quorum, so one probe box losing its route to an exchange is not recorded as that exchange going down. Quorum is a counting rule and it only holds while a majority can still see the venue; where a vantage point cannot measure this venue at all, its refusals are named below and left out of every number on the page rather than being left to a vote.

35 incidents over 60 measured days, grouped into 9 distinct faults. A component that fails the same way twice a week has one fault many times, not many faults, and a list that prints it once per firing hides the difference behind its own length.

Incidents are opened by up24's own state machine over its own measurements, not by Upbit's status page. One WebSocket carries every stream a venue publishes, so a dropped socket is recorded once, against the connection, rather than once per stream.
