Hi Rick,
My company is going to be doing some maintenance towards the end of the year so for grins I tried using the server hold option on my staging site. It didn't actually hold requests. I tried the same thing with only one server loaded. Still took the request and processed it. What am I missing?
You're likely logged in so you can get through. IOW the admins can still access.
Use another anonymous browser window or a different browser.

Ah. That makes sense. And I tried that and it does indeed work as expected when one is not recognized as the application king.
Whilst reading the fine documentation I noticed some other things.
For reference, this topic:
My web.config does not have a section for webConnectionErrorPages.
Should I add one?
If so, should I also add the entire config section as shown in the very fine help topic, or just add a key for the page(s) I want to override?
<webconnectionerrorpages>
<!-- NOTE: These settings apply only to the Web Connection Managed Module! -->
<add key="Exception" value=""></add>
<add key="OleError" value=""></add>
<add key="Timeout" value=""></add>
<add key="NoOutput" value=""></add>
<add key="Busy" value=""></add>
<add key="Maintenance" value=""></add>
<add key="InvalidRequestId" value=""></add>
<add key="TranmitFileFailure" value=""></add>
<add key="PostBufferSize" value=""></add>
</webconnectionerrorpages>
Thanks again.
Ah. Shall I send a feedback ticket for that help topic? 😃
Is there another mechanism to override the default maintenance page?
Nah it's already fixed in the docs. I removed it.
There's currently no way to override the error messages. This got pulled out when I went to MVC style templates and layouts - not really sure why because it would be relatively easy to make work with partial templates that load into the main _Layout template.

Thanks for confirming. Perhaps you can sneak that back in with 8.5 😃
Turns out I won't need to use the hold requests WWC page for this particular maintenance window but it would be nice to be able to customize that page.
