Hi Yagel,
If you have a proxy in place the best path forward would be to make this customization via the proxy server you're using due to the fact that the changes in BitBucket itself will revert after an upgrade, etc. Here are some resources you can use to create error pages in the environment you're using as a Proxy:
Apache Custom Error Responses
NGINX: Create Custom 404 / 403 Error Pages on Linux or Unix
Create a Custom HTTP Error Response (IIS 7)
Cheers,
Branden
