can you please let the 1.16 release team if you are going to be able to investigate and provide if you can help an approximate time for a fix?
Acked, I'm looking into the failure and will provide an update soon.
Fantastic! Thanks for the update
Yep, this is related to With service finalizer enabled by default, deleting the namespace (including services) now takes longer --- it now blocks on all the underlying load balancer resources to be cleaned up. It is expected that the latency for resource clean up might be longer on large cluster (such as in this test). I will soon send a PR to overwrite the  with something more reasonable in this case.
Sent to fix this.

Yesterday's run has failed due to problems with creating a test cluster. Hopefully we get an answer whether the fix has helped today.
Thanks for tracking this, seems like the latest run is green:
It looks good indeed, thanks /close
