UPDATE 6:57am Pacific: We are also adding Spunky email to the list of services that are down due to this, as some email accounts are hosted on that file server.

We have also discovered the cause for this downtime.  The shelves that hold this file server are redundantly powered, but it seems that both of the power supplies have taken a dive.  We are currently working to restore power to this shelf and hope to have that completed soon.  Check back here for more updates!

UPDATE 7:33am Pacific: We’re almost there!  We ended up replacing the shelf for this file server, as we discovered that one of the power strips died and the power supply connected to the hot strip was also dead!  So, this normally wouldn’t have caused an outage like this, save for the surprise dead power strip.  The file server is coming back online now and we’ll post the all clear here when we have completed some tests.

UPDATE 10:45am Pacific: The file server issues have been resolved and all services appear to be working correctly now. We are still however dealing with the newest status post about network issues we are dealing with.

http://www.dreamhoststatus.com/2009/06/08/emergency-network-outage/

So if you are noticing problems still it is likely related to that outage now. Sorry about the file server downtime. Typically our backup power supply would have saved us from this outage. This issue is resolved.

update: This issue appears to be resolved and only lasted for about 10-15 minutes.  We found that the ‘imapproxy’ service stopped running on a number of mail servers, as well as some issues with the SMTP service.  We re-initialized these services and they came back quickly.  If you are still having any issues, please feel free to contact Support and they will be happy to check!

NOTE: This will not effect your web servers, private servers or non-webmail e-mail accounts.

ADDENDUM: one side effect of the central database issues we have been having was the temporary loss of a large portion of our cloaking data table. Our admin team is in the process of restoring that information right now and expects to be done in the next couple of hours (2 PM PST was the original target but we just had another outage so we’re not 100% sure on when this will be completed). The good news is that you are not required to wait - if you prefer you may add the service back yourself via the panel here:

https://panel.dreamhost.com/index.cgi?tree=domain.manage&

and it should come back up once the DNS updates.

The DreamHost “we hate databases as much as you do” team!

UPDATE 1:10pm PST: The central database is back up again (as well as the control panel and WebMail interfaces. The admins are reviewing what they’ve found but don’t have a detailed update at this time.

We apologize for the inconvenience this is causing. It’s only affecting webmail sending, all other ones are fine. Please check back here for updates.

NOTE: This also effects access to our WebMail interfaces (SquirrelMail and RoundCube) and DreamHost Apps sites.

UPDATE: 11:28am PST It’s back up again! We’re keeping a close eye on the database server for a while though, just in case.

UPDATE: 12:16pm PST Looks like it’s down again. The admins are investigating. Stay tuned for more updates.

UPDATE: 12:40pm PST It’s UP again.

UPDATE: 12:57pm PST It’s down again. Admins are still investigating the cause of these outages.

UPDATE: 1:15pm PST It’s UP again.

UPDATE: 1:30pm PST Basically what’s happening is we’re 99% sure the memory (RAM) issue has been resolved. However the database process keeps dying without any useful information as to why. Fortunately however it seems to recover automatically in about 10 minutes or so without any data corruption (which is awesome). Our top database guru is on the case monitoring it very closely to try to figure it out and get it stable again. Again, we sincerely apologize for any inconvenience this is causing. We’re working as quickly as possible to get this problem resolved once and for all.

Update 4:43pm: All set! If you’re still having a problem with pan, please contact a dreamhost support robot!

Update: 12:15pm - This should be resolved now. The problem wasn’t with a plugin upgrade, but with our Squirrelmail database. Our admins fixed this up a short while ago and we’ve tested several customer accounts to insure that it is working again. If you continue to have problems with webmail, please contact support.

UPDATE 2:40 PM PDT **

Problems with central services have been resolved. Panel , webmail and other central services should be working as usual. There are still a few problems with the spunky clusters that may be causing outages for customers websites/ftp. These problems are also being fixed at this time and this post will be updated when those are fixed.

UPDATE 4:39 PM PDT **
All of the networking problems and spunky cluster problems have been resolved. We apologize again for the outage and if you are still having trouble feel free to contact support with the service you are having problems with.

UPDATE 5:11 PM PDT **
There have been reports of problems with the spunky cluster , we will re-open this status post until we have more information to what caused this problem. If you are on the spunky cluster and are experiencing downtime it is still due to the networking issue.

Update: Drooler is back up, and we will be monitoring the situation closely in case any further problems arise.

Update 4/8/08 4pm : We have added a new file server a couple of days ago and have another one on order. We continue spreading user data across the existing file servers, and are looking into possible user issue that are causing the servers to be unstable. Sorry about the inconvenience.
