Find the below mentioned article to check the sysvol replication

For logon once a DC gone down then you need to change the Primary DNS address on machine and change it to the ip address of working DC.
Create new GPO for testing on one domain controller and allow some time to replicate to all DCs

Then logon to all DCs one by one and open GPMC console, there right click domain and select change domain controller, select local DC and check if GPO is replicated there
If you don't found GPO within 3 HRS, it means your replication is not working

Also install DFS managemnet tools on domain controllers and run propogation test from dfs management console
It will tell you if replication is occuring or not

Check below post how to troubleshoot DFSR replication issues
