Now that our servers are all settled into their new home, we’re ready for phase two of our capacity expansion project.
Tonight at 7PM Pacific Time, we’ll be expanding our radio database cluster. This will give us lots of headroom for future growth and is the output of months of work and planning by the Pandora engineering team.
Like the datacenter move, this is a delicate process and requires that we put our system into “read only” mode while we do our work. Starting at 7PM, you will be able to listen to your existing stations, but you’ll not be able to create new stations, give us feedback on existing stations, or edit your account in any way. The system will be in this state for quite a long time — we estimate that it could be 12-15 hours before the new system is entirely populated and up, running, and able to take your station creation requests again. We estimate that the system will be back to normal at noon pacific time on Saturday June 10th.
We don’t like having to put the system into “read only” mode at all; it’s something that we always endeavor to avoid. Sadly there’s a small set of operations that simply require it. Last month’s datacenter move and tonight’s changes unfortunately fall into this category. Thanks in advance for your patience. While Pandora will stay the same on the surface for the time being, this change sets us up to scale to a much larger listener base and to bring more and more features online in the coming months.
Update 6AM, 6/10: Things are going according to plan and we’re making great progress. Thanks again for your patience.
Update 9AM, 6/10: The upgrade is complete and we’ve turned the new system on. We’ll be keeping a very close eye on things throughout the coming days. Everything went as planned with one caveat: some of you that created a station and later deleted the station may see the deleted station show back up in your stations list. This will only happen if someone had “shared” your station before you deleted it. We’re working on a fix to clean that up.
A tiny little surprise: There is one little feature in this release that a lot of folks have been asking about. Each song “slide” now shows the name of the album in addition to the name of the artist and song. Enjoy!

    Love the new album titles. One minor suggestion: lose the "by:" and "on:" labels. It's pretty obvious what they are.

    I love the new album titles. I really like that it tells me who the song is by and what album it's on. Pandora has introduced me to a lot of new artists and I would have a hard time knowing which is the song name and which is the group name if it didn't have the labels. Thank you for all the work you do. I'm still addicted and still telling everyone I know to come check it out.
