fab.wmflabs.org will be taken down this Monday 18:00UTC. Locally save tasks or workboards that you might rely on for the week. Verify your email address in fab.wmflabs.org if it's not already. The intention is for the Phabricator production instance to be available by Sept 12th.
The Phabricator instance on fab.wmflabs.org has been used over the last few months for both real and test data. On Mon, Sept 8th 2014 18:00UTC this instance will be made unavailable to migrate content to the upcoming production instance on phabricator.wikimedia.org. The Labs instance will not come back online in the same form, if at all.
We take the Labs instance down because we cannot make the Labs instance read-only while dumping its data. Neither can we easily display a banner on all pages warning you to not make any changes which would get lost anyway.
Tickets from the following projects are marked for migration:
For questions catch us (chasemp and andre__) on Freenode IRC or drop into the #wikimedia-devtools channel.
