Setting multiple Apache2 VirtualHosts to use same DocumentRoot?

Question

First, this seems to be working fine on my server, but I am wondering about any "unknown" implications, especially any public-facing problems that could occur, such as "Google now hates your server..."

I have about 10 domains which are just serving a simple "We're offline" message.

I want all of these "offline" <VirtualHosts> to use the same <DocumentRoot>, like so:

<VirtualHost *:80>
      ServerName example1.com
      ServerAlias www.example1.com
      DocumentRoot /www/_offline.com
   <Directory /www/_offline.com>
      ...[snip]...
   </Directory>
</VirtualHost>

<VirtualHost *:80>
      ServerName example2.com
      ServerAlias www.example2.com
      DocumentRoot /www/_offline.com
   <Directory /www/_offline.com>
      ...[snip]...
   </Directory>
</VirtualHost>

Am I going to have any problems with this setup, or is this actually okay?

This should be fine. You can optimise this somewhat by just using ServerAlias directives for all of your FQDNs in the one vhost, but it's not required.
