I'm sure users of that server that use these message boards would post their own messages asking why the server was down or unreachable. Then of course your informative post would be legitimate. However, for what I can only assume is a (very?) small server, the chances of your post being beneficial is small and you should have a website to post such news on. You can get free ones if you do not wish to pay.
My 2 cents.
