Site loads fine, although a connection to database could not be established.
As per announced at http://status.x10hosting.com/ Lotus (your server) is getting new hardware which would account for some of the downtime. It is possible that the database connection is down due to this as well, though the first step would be to verify that you have 'localhost' set as database host in your script. If there were any changes to how the database can be accessed that'll be the only thing that works.
