From status.dreamhost.com:
We just had a drop in our network for about half our servers.. if you can’t access your site or email now, please hold on..
Very nice. Even their status page was down for a good while earlier. Point at hand: buyer beware. You get what you pay for with dreamhost. If you’re not serious about uptimes, don’t mess with dreamhost.
The rest of the log from tonight:

We’re still actively trying to diagnose and fix the problem.. it seems to possibly be a physical problem with one of the fiber cables between two of our data centers. We’ll post further updates here as we progress. Thank you very much for your patience and we apologize for the downtime this is causing.

Scratch that.. it turned out to be a failure in one of our 10 gigabit network interfaces. We’ve swapped it out for a spare one and everything looks back up and running! There may be some residual problems where some servers need to be rebooted, however the root cause of the problem is fixed. Please let us know if you are still experiencing any further problems! Our apologies again..
