There was a planned 3 hour outage tonight for maintenance reasons. Unfortunately, the duration of this outage has been somewhat longer than planned. See the link below for more details. Although, the status site only loads intermittently for me at the moment, I guess because it is being hammered by frustrated customers.
Hopefully, things will be rectified soon and all DreamHost services will be back up (fingers crossed).
