A stream has no latency of its own — a feed either delivers or it does not — so this is Upbit's REST endpoints over the same window, per minute, as the median across them. It answers the question the timeline cannot: whether the rest of the exchange was fine while this feed was down.
DID UPBIT SAY SO?
Upbit publishes no machine-readable status feed, so there is nothing to compare this against — everything on this page is up24's own measurement.
up24 opened 36 incidents for Upbit in the last 90 days. Nothing Upbit published lines up with any of them.
