 1. ``distributed_api_test`` - checks general API functionality and should finish very quickly (< 1 minute)
 2. ``train_*`` - checks single trial training on different setups.
 3. ``tune_*`` - checks multi trial training via Ray Tune.
-4. ``ft_*`` - checks fault tolerance. **These tests are currently flaky**
+4. ``ft_*`` - checks fault tolerance.
 
 Generally the releaser tool will run all tests in parallel, but if you do
 it sequentially, be sure to do it in the order above. If ``train_*`` fails,
 ``tune_*`` will fail, too.
 
-Flaky fault tolerance tests
----------------------------
-The fault tolerance tests are currently flaky. In some runs, more nodes die
-than expected, causing the test to fail. In other cases, the re-scheduled
-actors become available too soon after crashing, causing the assertions to
-fail. Please consider re-running the test a couple of times or contact the
-test owner with outputs from the tests for further questions.

 Acceptance criteria
 -------------------
 These tests are considered passing when they throw no error at the end of
