i have 2 production site. design new sql server 2016 alwayson infrastructure. have designed multi-site cluster below.

there asynchoronous replication between node1, node3 , node4 disaster recovery

there asynchronous replication between node1, node3 , node4 disaster recovery

i have questions;

1) if our wan line drop, cluster goes down?

2) if need have witness, can store witness? (btw, have third location. can store witness @ third site)

3) think design below? can have possiblity trouble design in future?
