I have installed a few boards and CMSs last days using "one-click" install and everytime the DBs were up in less than 5 min even during the day! They are not reachable through phpMyAdmin though, that usually takes around 24h.
I read a sugestion from someone here on the boards and found it very usefull: for each domain you host here, create a few DBs as standby, like that when you need one, you will be working full power in no time.
