[FX.php List] "site down for maintenance" include?

[Joel Shapiro]

Hi all

Has anybody implemented a procedure to automatically alert users when  
a site is down due to the FM files being closed on FMSA?

I'm thinking an include on every page that could check if the DB is  
available, and if not, present a friendly message to site-visitors  
and then a php exit;

Would this work?  Is there a specific FX error to easily check for?

This would be for when the DB needs to be closed for updating, etc.

Thanks,
-Joel
