You may have noticed that the Foxmarks bookmark synchronization extension was posted to the Firefox addons site yesterday. Grats Todd!

What you might not know is that the server where Foxmarks stores your bookmarks is an instance of Cosmo 0.2. This is the first production deployment of Cosmo (that we’re aware of), and we’re pretty excited that it’s holding up.

Granted, Foxmarks doesn’t stress the server anywhere near as much as a calendar shared by Cosmo, but this real world usage has been a huge help in identifying issues related to security, performance, scalability and data migration that we otherwise wouldn’t have had to cope with this early in development.

In fact, we’ve successfully tested Foxmarks and Cosmo with many tens of thousands of users, so I hope to see Foxmarks’ popularity continue to rise. We’ll do our best to keep the server running well and minimize breakage and downtime as we move to subsequent Cosmo releases.

Cosmo 0.2.7 is ready for download at http://downloads.osafoundation.org/cosmo/releases/0.2/.

0.2.7 fixes two critical data consistency issues:

• PUTs aborted partway through the process caused Cosmo to store the partial file and return a success response rather than failing as expected [5078]
• Simultaneous signup operations could fail, resulting in broken accounts without home directories in the repository [5095]
