Hello all users of Airflow,

We need to upgrade airflow on all of our Airflow instances, so I'm scheduling a maintenance window for tomorrow, Wednesday November 29th at 10:30 UTC and I expect the work to take no more than 30 minutes.

I will pause all active DAGs on all Airflow instances prior to the work, allow some time for running tasks to complete, then resume the DAGs afterwards.
Naturally, you are also free to pause your own DAGs prior to the maintenance and resume them afterwards, should you wish to minimize the risk of disruption.

Please do let me know if there is anything specific that you would like me to check, either before or after this maintenance.

Kind regards,
Ben
