As the assignee, review the issue and decide on one of the following actions:

• The flake is a critical bug -> Fix the bug immediately, move this issue to in "In Progress", and keep it open until the testcase does not fail anymore
• The flake is non-critical -> Quarantine it (assigning [QUARANTINE] tag to test name), close this issue, and create a follow up to take the issue out of quarantine
• There was an infrastructure issue (anything "below" the testcase) -> Move the issue to "Obsolete"
