Etsy’s CTO Chad Dickerson said:

I’m just completing my seventh week as CTO here at Etsy, and the Engineering Team here is continuing to work on the infrastructure for the site, including putting in some new systems and processes in place that will make Etsy more reliable both for the holidays and for the long haul. Next weekend, we will be migrating Etsy’s master database to better and faster hardware. Since the master database contains the most essential information used to run Etsy, the key functions of the site will be unavailable. We have scheduled this maintenance for 3am until 6am ET on Monday, October 27, 2008. We will have a page up noting that we are in maintenance mode, but you will be unable to use search, listings, checkout, Storque, forums, convos, or anything else you normally use at Etsy. Because this is a significant migration, we wanted to give you plenty of advance notice.

This weekend, we will be taking the Storque database down for maintenance from 11pm-midnight on Sunday, October 19, 2008. Storque will be unavailable during this time.

You might notice that the maintenance window for the master database is 3 hours, whereas the maintenance window for the much smaller conversations database on September 22 was much longer (approximately 11 hours). This is not a coincidence, but very intentional and the result of better planning and execution. Since September 22, we have begun putting a more thoughtful and intelligent design in place for our database systems with the specific goal of shortening maintenance windows and any downtime you will experience. As we continue to work on Etsy, we will do whatever we can to minimize the disruption for all of you.

For both of these maintenance windows, we will be posting updates to fix.etsy.com.

Thanks for your patience as we continue to work to make Etsy better!
