We’re continuing our roll-out of Ubuntu 12.04 Precise to an additional 150 web servers this Sunday, October 5th. As we’d like to get all of our customers over to this new OS, we’re planning on running these upgrades in larger batches. While the total estimated maintenance is 5 hours, we expect actual downtime due to the upgrade to be around 30 minutes. A large part of the maintenance window will be spent testing all of the servers post-upgrade to ensure everything is in order.
As the Ubuntu image will not support PHP5.2, anyone who still has this version of PHP selected in the panel will be migrated to a Debian server before these web servers are upgraded, and will still have until the November deadline to upgrade to a more recent version of PHP.
While this upgrade process is expected to go smoothly, there are some things you can do to reduce the chances of additional service interruption. Customers running Ruby or Python applications should ensure that they are not linking to static versions of any required libraries, as library versions will change. Customers running custom PHP.ini setups should ensure they are pointing to PHP5.3 or higher as the PHP5.2 executable will not be present within Ubuntu.
Here is the list of web servers to be upgraded. You can check if you’re one of these web servers by clicking the ‘Account Status’ link within the DreamHost panel and looking for ‘web server’:
If you have any concerns leading up to the upgrade, please don’t hesitate to contact our support team. They’ll be more than happy to answer any questions you might have!
While the upgrade is ongoing, we’ll keep this post up-to-date with new information as it becomes available. If you’d like to know more about the benefits resulting from our switch to Ubuntu, please read this post.
Update October 6th, 2014: 1:23AM PDT: All web servers are back online other than the ‘vroomfondel’ web server which is being restored to Debian due to latent hardware issues. Baratheon, vroomfondel and zem will not be upgraded tonight.
