Hello, everyone.

Can you, please, help me with this case:  
There are two instances of Alertmanager, each with its own routing settings (each has its own grouping logic and its own receivers). Each of them receives same alerts.

I need to share silences between both instances. After combining them into a cluster, will each node continue to send notifications independently, but adhere to the general silences list?
