For a bit of schadenfreude, do a Titter search for Dreamhost right now. It's a fire hose of complaints.
We apologize for the downtime as our core network is offline at the moment.
...but the latest timestamped update says it's not:
Update: 7:28pm (Pacific):The network is confirmedly looking much better, but we continue keeping an eye on it. If you’re still having any issues, please submit a ticket with as much details as you can provide, so we can use that to evaluate if your case is unrelated or if there is still something else lurking around waiting to be fixed. We’ll update again as the evening progresses, but so far so good. We very much appreciate your patience and understanding regarding this outage.
Some of my sites are offline (now I know that pingdom really is active at least!). Luckily they are personal, non-critical sites. It's the first serious outage I've had since joining 8 months ago.
