Mine have been hellishly slow, too. And now, all the sites are completely down. Of course, there's no mention of outages or slowness on the status page or twitter, which is also pretty much par for the course. You have to dig for info at DH, or just wait until they fix something and send you snarky reply emails that blame you for the lack of service.
(For instance, my VPS will occasionally just go crazy and restart, even though I get virtually no traffic. But that's apparently my fault, according to numerous emails from "support".)
I hear you, simguybar.
