How this works

Any serious bugs affecting wmf.26 should be added as subtasks beneath this one.
- Use this form to create one.
Any open subtask(s) block the train from moving forward. This means no further deployments until the blockers are resolved.
If something is serious enough to warrant a rollback then you should bring it to the attention of deployers on the #wikimedia-operations IRC channel.
If you have a risky change in this week's train add a comment to this task using the Risky patch template
For more info about deployment blockers, see Holding the train.
