MAINTENANCE_PAGE_URL
Configuration variable on your app:
Custom Maintenance Page
if you set one up, and fallback to a generic Aptible error page if you did not.
You usually shouldn’t need to, but you can identify responses coming from Brickwall through their Server
header, which will be set to brickwall
. Brickwall returns a 502
error code which is not configurable.
If your Service is scaled up, but all app Containers appear down, Aptible will route your traffic to all containers.
