We’re going to bring OpenLibrary.org offline at around 3PM Pacific Time to upgrade our database server. If all goes according to plan, this upgrade should take approximately three hours. We’ll be replacing our old spinning platter disks with modern solid state drives as part of a broader effort to improve the overall performance and reliability of the Open Library system.

We’ll post updates if they come to hand.

6PM UPDATE – Looks like it’s going to take a wee bit longer than expected to get everything copied over. And by “wee bit,” we mean another hour or so from now. If the database decides it wants to move slower, we’ll update again. Thanks so much for your patience!

7.45PM UPDATE – And, we’re back!
