LOL that’s funny.
well, I can tell you that there arn’t routine downtimes on the servers here. Backups are made on a regular basis, (you can access the .snapshot directory for a backup one or two hours old, one or two days old, and one or two weeks old). There’s no lag when backups are made becuase of the network structure Dreamhost Uses. You data isn’t actually stored in the same physical box that is your web server. Dito for Databases and E-mail services.
However, the problem you may encounter is when a server does fritz out. Most of the time DH is very good about getting things reslved quickly, but from time to time services will go out for a couple of hours. I personaly have only expirenced major down time like this when the lights went out in LA, but that’s not the case for everyone.
So, if you can live with your server going out for for 2 or 3 hours once a year (making WILD guesses here) then DH will be just great for you. If one such outage is going to send you looking for an other host, you should be looking for dedicated hosting.
Hope that helps
