Hi,
When our publish instances are going maintenance live traffic is seeing below message for the traffic which is excluded in CDN caching. Where can I find this page? I am assuming it's some default page html file in dispatcher, if not any advice on how to implement a custom html will help.
Goal is when publish instances are unavailable instead of showing below page I want to be able to customize it.
