  We are performing a series of system updates for security and stability reasons. The updates have undergone testing on development and preview systems, and are gradually performed on all systems in scope. All systems in scope are in cluster / high-availability configuration.
During the upgrade, machines are taken out of the regular mailflow, and are re-integrated into the mailflow after the upgrades are done and functionality has been tested.
We do not expect any impact on overall system stability or performance.
