Focal has MySQL version 8.0.20-0ubuntu0.20.04.1 which sets group_replication_member_expel_timeout to 0 by default [0]. As a result, cluster members are expelled from the cluster 5 seconds after the loss of connectivity. This proves to be too short for our CI and some other environments in the wild. MySQL documentation for this option suggests that 5 or even 10 seconds may be too low for congested or overcommitted environments which happens to be the case. As of MySQL 8.0.21 the default for group_replication_member_expel_timeout is set to 5 seconds.
