    During this window, we will transition services for merchants who experienced callback delivery issues following our recent infrastructure move. This change will restore their service to the previous environment to ensure stability.

    Impact

    • Downtime: Affected merchants may experience up to two separate 1-minute intervals of downtime during the window.

    • Affected Users: This maintenance only impacts selected merchants integrated with the Checkout API.
