What is Maintenance Mode?

Maintenance mode works in two layers. On the panel side, the maintenance flag is written to the site and shown as maintenance status in the interface. On the WordPress plugin side, the local maintenance option puts the main site on a 503 page while leaving the heartbeat endpoint accessible.

In care

Open both layers during scheduled maintenance.

The panel labels the status as "In Maintenance" on the maintenance flag monitoring screen. It is recommended to also enable maintenance mode on the plugin side to avoid false alarms.

Turning on Maintenance Mode

  • Panel: The Maintenance Mode switch on the site edit screen updates the maintenance status.
  • Plugin: The Maintenance Mode card on the Admin screen turns on local maintenance mode and attempts to synchronize with the dashboard.

There is no time limit or automatic shutdown. When maintenance is finished, you need to switch off manually on both sides.

Maintenance Mode with API

POST /sites/{site}/maintenance

cURL
curl -X POST https://status.anchoruptime.com/api/v1/sites/{site}/maintenance \ -H "Authorization: Bearer dku_a1b2c3d4_4f8b91c2e8d04b46a1d7f2aa6c93e5fd" \ -H "Content-Type: application/json" \ -d '{"active":true}'

Request body field is validated as active, not enabled. Successful response returns ok=true and active.

Things to Consider

Do not leave maintenance mode on.

Plugin local maintenance mode returns 503 and X-AU-Maintenance header in the main URL. If this state stays on for a long time it can distort your real health signal; turn it off on the panel and plugin side when maintenance is finished.
