That error only means one thing: database connection detials are wrong. See Editing wp-config.php « WordPress Codex
If that error appeared without you doing anything, ask your host if the database server is running OK.
Error establishing a database connection
This either means that the username and password information in your wp-config.php file is incorrect or we can’t contact the database server at localhost. This could mean your host’s database server is down.
Are you sure you have the correct username and password?
Are you sure that you have typed the correct hostname?
Are you sure that the database server is running?

@kpalaniswamy,
Regardless of how similar your symptom may be, you should create your own thread out of courtesy.
Thanks again everyone for you feedback. Come to find out after talking to our host that they had added/switched servers and had failed to point our site and others to the new server. Everything is back to normal now.
Thanks again for your help
Tom
