Hi Ajit, Juraj,

For simplicity, we will keep the functional and performance testing disa= ble during the weekend.

In this way, you will have no tes= ting interfere with you during troubleshooting.

Then we w= ill rerun all the jobs that are skipped.

Please le= t me know if you have any questions.

Best,
