Investigating why I didn't get a TryBot result for https://go-review.googlesource.com/c/tools/+/419954, I see that there was actually a new failure mode on linux-arm*-aws builders: err=unknown EC2 vm type: m6g.xlarge-standard-16

Questions:

  • what is this failure?
  • why didn't I get a TryBot result? Is this failure mode prevent normal processing of the results?

I'll see if I can re-run trybots, but wanted to capture the failure mode.

Err, TryBots just restarted, so maybe coordinator is being deployed... (perhaps I should have waited a bit before filing...)

This is being fixed by CL 420755 right now.

Great, will leave this open for visibility and close after TryBots pass.

Seems like this is fixed now. At least, my TryBots passed. @dmitshur do you want to leave this up a bit longer? It seems some of the backlog is still being processed?

I agree the AWS builder issue is resolved (e.g., trybots passed on CL 420816), so let's mark this as closed to reflect current status. (We can unpin it a bit later.)
