last flake on sig-release-master-blocking testgrid is 03-05 As it does not flake on the board anymore and still flake in other CIs, remove it from release signal board.
/assign Based on , I don't see it flaking as far as history exists. It seemed to have started flaking around March/April 2023. This also corresponds to when aggregated discovery was enabled by default so it may be related. Will do some more digging.

Hey Is this issue fixed? If yes, from which version of kubernetes will this fix be available from?
This still flakes in some CIs. The flake rate is very low, but it is a conformance test.
Thanks for the quick response. I see it is very flaky. Is there any active work going on to fix this? If yes, is there any estimated time by which it could be fixed?
do you have some update on this?
