Hi, one of my WP sites suddenly came up with a database connection error. See:
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 db1716.perfora.net. This could mean your host's database server is down.
I verified with hosting service that the server is running. The database was connecting fine with the credentials before (for years). I updated the credentials just to double check, and updated wordpress (via FTP, since I can't log in).
Any ideas? This is an important news site in Egypt - it's not impossible something was hacked, but I'm not sure how that would cause a db issue.
