I have sites I manage on several different hosting services, and GoDaddy was one of the trouble-free ones in my case. Configuration worked (I can't remember now if it needed the 5 minute window or not) and the Firewall has been in learning mode, is set to switch today to enabled mode on at least 5 sites, one of which is a multisite install.
I have had issues on Siteground, Hostgator (though that one is working now), and others, but bit by bit the issues are being worked out.
In all GoDaddy cases, I'm using the recommended server configuration,and the default setup options...it just worked.
