I just signed up for Dreamhost on Friday night. The client site that I migrated over was loading really fast Saturday-Sunday but it started slowing down on yesterday, and today is even worse! I was even receiving 505 Server Errors this afternoon.
It's a Wordpress website and DH is claiming that this website with only 5 or so pages and 3 blog posts is hitting the memory limit. I understand that Wordpress sites may strain the resources, but this site hasn't even gone live.
The site is located on their Virginia Data Center. Where are your sites located?
