I've been using WP for err, well, over four years now since early 1.x versions. Never had a problem with it. I've also been using Dreamhost for that long, never had a problem with them either.
This past week, particularly in the evenings, my sites give me 503 and 500 server errors, and I mailed them about it. They responded by saying their prochost script said my user (which all the blogs ran under) was using too many resources. So last night I installed cache plugins, as their help files suggested, and I also created new users and moved different blogs to them to spread the load about.
Tonight: same issue. All of the blogs in question are now down, 500 internal server errors. I mailed them, barely keeping it civil since I'm getting really angry about it. I know they'll just come back blaming me saying nothing on their side has changed, which is nonsense.
I wonder if anyone has any good hosts to suggest? I run about 15 blogs. Of those, about 7 or 8 are visible, the others are just testing blogs for me and they only get about 3 visits a day. Also, any good hints on cleaning up blogs, aside from the plugins? I know a few, just wondered if I could learn some more.
Hope someone can help!
