Hi,
I've SQL server 2019 STD always on set up with 2 nodes and file share witness (located on third server). yesterday we had an network issue that the main switch was down for 15 minutes. after the network is back i see that the whole SQL server alwayson cluster was deleted from the computers completely. how this thing can be happened at all?

That cannot happen just because of a network outage - if the configuration was altered and the cluster removed, it was because someone removed it.
I would bet something else is going on but there isn't enough information.

Please make sure the cluster service is up and running on your replicas.
Thanks
