Will it be replicate while Site1 is down? By my logic it should be enabled site lnik bridge between site2 and site3 to successfully replicate without site1.. Am I wrong? But there is no such an answer and there is no info about it has already been enabled..

Hmm. Okay.. Found explanation: As SiteLInkBridging is Enabled by default, Site2 and Site3 are connected through Site1. So replication from Site2 to Site3 go through Site1 even if no DC in Site1 is available
