It seems like I have about one serious problem with my hosting service every month. Since I signed up in fall of 2007 the mail server has backed up at least twice, causing email from customers to be delayed in excess of 24 hours.
I’d say about 25% of the time I try to load a page from my website it is either completely unresponsive, or bad enough that no customer is going to stick around long. My server, Dione, is under consistently high load.
I’ve invested money in advertising to drive traffic to my site, and it is very frustrating to think of a potential customer arriving at an unresponsive website.
My site is very low traffic, low bandwidth, but each individual lead from the site is potentially worth thousands to me. There are lots of things I like about DreamHost, but I honestly cannot recommend it for someone who is going to rely on uptime to run a business.
