Hi,
I just recently setup tailscale for accessing all my self-hosted fun stuff while I am away from home as securely and conveniently as possible. It dawned on me today that it’s entirely possible that tailscale can have an outage one day, and at that time I would need a backup. So I searched around and the best open source alternative with the same concept I could find was zerotier. So, I have a few questions for you.
#1. Can I use zerotier alongside Tailscale for backup connections in the scenario I described? If so, should I?
#2. What is your backup method you currently have set up?
