Is it "safe" to reboot my compute instance from the EC2 dashboard?

Datomic cloud is spitting out a bunch of strange errors and I wonder if it just needs to be kicked a little.

I actually went and read the docs and turned my autoscaling group to capacity 0, then back up to 1 to achieve a reboot. So far, no error messages.
It's generally safe to kill/terminate and let auto scaling reboot. Just know that if that's your last instance your app deployed via ions or transact might error with no compute to serve. I do the scale up to 3 and kill a problematic instance once my 3rd is up but that's when I am prioritizing up time.
But the point is the compute machines are designed to be ephemeral. If you're on the I3 etc series and using valcache you'll also see a slight performance hit while caches warm up

Got it
