No idea. The dashboard says it's running and fine, sometimes the shell console is ok, sometimes it's also bogged down, but the instance is completely non-responsive from outside. The other instance I have in the same tenancy but a different fault domain is perfectly fine, so I don't know if that's related somehow. I'm running Pangolin on it to forward a couple things, one of them is higher throughput than I had expected, but rebooting makes it come back, so I don't think they're throttling me.

I'm kind of at a loss, but I threw together a webhook to use their API to reboot it when it stops responding and that seems to be working while not actually addressing whatever the root cause is.
