What is the difference between Advance Grade and Standard Grade Servers?

Both plans run on servers with slightly differ configuration. However, Advance Grade servers holds less customers per server than Standard Grade servers. This has several benefits for Advance Grade user:

1) The server load is generally lower than any Standard Grade Servers.
2) Backups, which are done weekly, slow down servers considerably. When there are less users on a server, Backups are done faster. Therefore, the period that the server may encounter slowdowns on a weekly basis is greatly minimized.
3) Every user on the server holds some responsibility in making sure the server is operating in proper conditions. Improper scripts and lack of knowledge in web site maintenance on the side of our customers could lead into server issues on our side. While we have years of experience in dealing with these issues, on a Advance Grade, because there are less customers, you will experience less "hiccups" when a customer uses an improper script or decides to experiment with a new application
