I’ve red a lot of similar topics.
Some people reported: switching to IPv6 helped!
Also it depends, what country you are in?
For me:
- self hosting a private root server
solved all stability problem.
But it is not working with Apple devices.
And it took me:
- 2 years to learn enough about: how to manage linux VPS systems
(firewall rules, docker, etc.) - Plus ca 3-400 hours learning about ZeroTier + ZTnet and testing everything.
(like: how to create gateway-delete script to fix the internet)
