With our ongoing hosting issues due to massive traffic increases and failing hardware we’ve been too distracted trying to manage those issues to finish all of the testing for the schema change release that was scheduled for today.
We deeply regret having to do this, but we’re going to delay the schema change release by a week. It is now scheduled for May 23, 2016. This week long delay will give us a chance to further tweak our server configuration (more on this in the next blog post) and to test the schema change release in much more detail.
We are, however, going to upgrade our database server to Postgres 9.5 either later today or tomorrow. During this upgrade we are going to employ a back-up database server and keep MusicBrainz running in read-only mode with a slightly reduced overall capacity (I’m sure everyone know what that means by now). This upgrade should have no other effects on our downstream data users.
We will give people plenty of notice before we start the postgres upgrade via our site banner and via our Twitter account (@musicbrainz).
Sorry for the continued drama affecting our services — we’re working hard to keep things together!
