Dreamhost Clients – Possible 500 Errors During Database Migration

This morning Dreamhost released an email to a number of clients notifying them that a database was being moved to a new server. If you’re one of our clients and you receive Website Disabled warnings its likely being generated from this temporary outage.

Please allow the the scanner to run again, once the database server is back up it should update the scanner on the next run.

Here is the message from Dreamshost:

DreamHost MySQL server ‘porbeagle’ being moved to new hardware

You are receiving this message because your web/MySQL hosting services are being affected by hardware maintenance due to issues with your MySQL hosting server porbeagle.

Due to issues with the RAID controller, we are replacing the hardware for this server and will be restoring all data from our backup server to the new hardware. We’ve completed all the work to get the server mounted and the file restore started, and MySQL services are starting up shortly to bring sites back online. In the meantime you may be experiencing downtime with your websites or may be unable to access your MySQL server. We apologize for the inconvenience, and we will update this post in the next hour or as soon as progress is made, whichever is sooner.

A little bit about the restore process: once the backup connection is established, we will reload your MySQL service and will serve your databases again using the data on the backup server. The data will be mounted over the network to allow your MySQL services to remain online for the duration of the process.

During the restore process, there may be periods of high load on the server due to the large amount of data being sent to the new server. We will be closely monitoring the server and mitigating that load whenever possible.

Please note, we‚re only able to monitor the status of the server and that of the MySQL services responsible for your sites and not individual sites and users. If you‚re still having trouble loading your sites or accessing your server, please let us know the specifics, so we can take a look for you. You may contact us either by replying to this message from your inbox, or by submitting a support ticket in the DreamHost panel (https://panel.dreamhost.com/), under Support/Contact Support.

This notice will also appear on that page in your DreamHost Panel and will be updated throughout the process with the latest details we can provide.

This incident is only related to the shared MySQL server porbeagle, and no other servers or services (such as Web or email) are affected.

If you have any questions feel free to contact us at info@sucuri.net.
