  • We recorded 5 outages of five minutes or longer; the longest, 11m 45s, was at Kraken.

How to read and cite this report

Availability is the share of checks to each exchange's public time, market-data and order-book APIs that returned a valid answer, measured from Tokyo, JP. It says nothing about order execution, withdrawals or the safety of funds, and another location may see different results.
