Where is 'maintenance' page?

[bpeddapudi]

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.

@bpeddapudi When the server is down , obviously request cannot be served from the Publish , hence we have to host the Maintenance page somewhere outside and redirect dispatcher to those URLs. We can acheive it by having static pages in either S3 or Azure
