Thank you for shedding light to this key topic, @cryptographic .
As actifit witness, we had our witness running previously on hetzner back in steem days, but as of hive, we moved it to privex team, their service is quite reliable.
We do not prefer running on our own home connection as the potential for Internet loss is at stake, so from a service continuity and reliability basis this is more optimal.
Thank you for the reply. It's another valuable data point that needs to be included!
