Bitbucket will be unavailable up to one hour starting Sunday, September 30, 2012 at 01:00 GMT.
During this maintenance window we will upgrade from PostgreSQL 9.0.x to 9.2.1, which allows Bitbucket to take advantage of several performance improvements. As part of this migration, we are now utilizing Bucardo to replicate between major versions of Postgres, which saves us downtime over previous migrations.
Thanks for your patience as we work to increase Bitbucket’s performance and reliability.
