Network partition. A network partition is equivalent to multiple site failures from the perspective of the coordinator. If a network partition occurs before the coordinator transmits its commit decision, the participant sites that become disconnected unilaterally abort as in case 1(A), and the coordinator commits as in case 1(C). If a network partition occurs after the coordinator has transmitted its decision, participants receiving the commit message will locally commit; upon timeout expiration the coordinator will record in its Rec Info requests for reconciliation for participants that committed but did not successfully transmit an acknowledgement to the coordinator. As the description shows, all sites with no local failures may commit a transaction.
