Pandora Server Upgrade – 7PM, Friday June 9th

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!

  1. That explains my confusion! I noticed both your “tiny surprise” and went looking for other changes, and a deleted station that showed up for awhile then disappeared again. Congrats again for a superb and awesome music service. I’m addicted. Part of my routine in starting my computer!

  2. Pandora is really amazing. can’t express just how much i am hooked to it. what an initiative,people. thanks for your work and keep going on!

  3. Pandora is such a great idea! Well done. I listen to Pandora all day, everyday at work. It’s sometime hard to concentrate as I always want to check out who is playing. I discovered so much through Pandora. Thank you for your work and for keeping this free!
    Also, thanks for the new features!
    Any plans in adding some french music?

  4. Just one complaint: After your latest change to the album covers, the artists’ names are truncated. (The album names also are truncated, but I care less about that.)

  5. Truly amazing project. My students have begun to ask me “Who is it this morning Mr. W?” when they walk into class. This is remarkable and only getting better.
    One question; where’s the best place to leave listening suggestions? I’ve got 400+ CDs and I’ve put in some jazz names that haven’t found a match. Rock hits have been dead on. Can’t wait for classical to get up and running.
    Thanks a MILLION for your efforts.

  6. WOW! I love that you guys also made it so that titles now scroll when there is overflow, instead of disappearing behind the album cover. The new menu confused the crap out of me for a minute – for some reason I couldn’t figure out what it was that I was looking at, but i got used to it.
    =) Thanks for all you do!

  7. Thank you for the update. Hard to believe that anything so good could get any better. In fact this thread reminded me to subscribe in order to support your ongoing efforts.
    Thank you again for your hard work.

  8. Love the new album titles. One minor suggestion: lose the “by:” and “on:” labels. It’s pretty obvious what they are.

  9. 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.

  10. This is the most intuitive and fun internet radio ever…I have more staions than there are genres of music, i think…SOO cool. Thanks!

  11. Thank You-Thank You-Thank You-Thank You-Thank You ….. It’s like you’re in my head!!!!Scarey Isn’t it.
