Have been ripping my hair out because `tailscale up` is not working.
Turns out there is a major outage.
Just trying to help other devs who have almost thrown the computer out of the window today, because of that.
Had the same experience. I happened to have rebooted during the outage, and spent like half an hour checking DNS settings, etc for why tailscale wouldn't start, until I realized it wasn't my problem. Really hope they had better error messages instead of letting `tailscale up` hang forever.
