I had trouble reading my mail and you might as well had trouble accessing this site. Evidently Dreamhost was dealing with a distributed denial of service attack.
I liked the way they updated their status page humourously. Some other admins would have been hopping mad.
I don’t run anything too critical on Dreamhost. Though I often suggest companies outsource their mail to them. So if I was using Dreamhost for managing a company’s IT needs, the company’s email et al would have been out of action for half the day.
