ReleaseEngineering/How To/Close or Open the Tree

• Warn #developers IRC channel and the sheriffs.
• Use https://treestatus.mozilla.org/ to close the trees.
  • Please use the "Remember previous state" option, so you can easily restore the previous status messages when you are finished (there will be a restore button at the bottom of the page).
  • In order to change tree statuses, your browserID email needs to be added with sheriff permissions (ping edmorley/philor/catlee or ask in #developers).
• Reload TreeStatus to confirm the status has changed.

The following trees at minimum should be closed when there is a general infrastructure problem

• mozilla-central
• mozilla-inbound
• mozilla-aurora
• mozilla-beta
• mozilla-esr*
• mozilla-b2g*
• gaia -- treestatus plus the following:
  • While Gaia is listed on Treestatus, it's a no-op closure from there (mainly useful to consumers of the Treestatus API for knowing the current state).
  • To actually close Gaia, someone in the Owners group will need to go the Github settings page and remove the Chefs and Cooks teams from the collaborators listing
  • Once the event is over, those teams can be re-added to "open" Gaia once again.
