@asbear -These are Great questions people should be asking.

I have 3 witness nodes in 3 different data centers on 3 different continents.
1 Full Public RPC Node
1 Seed node

1 of our witness nodes was located in one of the datacenters that went offline lastnight, and our failover switch kicked in and our first backup at different datacenter took over immediately.

It is very very very important to have backups in different DC's for just this type of thing
