From the European supervisor's market report of March 2021, which is the one document listing these episodes together. Durations are as published; several are not stated. No significance statistic applies.

The United Kingdom regulator counts seven outages across European trading venues in 2020 and 2021. Its own study and an industry study both found that trading did not migrate to alternative venues while the primary market was unavailable.
