👋 Friendly reminder that deploy blockers are time-sensitive ⏱ issues! Check out the open Staging deploy checklist to see the list of PRs included in this release, then work quickly on the following:

1. If you find which PR caused the issue/bug, you can reassign it to the person responsible for it.
   • If the author is OOO or won’t get online before the daily deploy is due, you are responsible for finding the best fix/path forward. Don’t hesitate to ask for help!
2. Try to reproduce the issue, if the bug is on production, remove the DeployBlocker label but stay assigned to fix it (or find out which PR broke it to get help from the author).
   • You can adjust the urgency of the issue to better represent the gravity of the bug.
   • If the issue is super low priority, feel free to un-assign yourself.
   • Be careful with PHP warnings, sometimes it is more complex than just adding a null coalescing operator as they might be uncovering some bigger bug.
   • If it was a one-off issue that requires no action (for example, Bedrock was down or it is a duplicated issue), you can close it.

Remember rule #2: Never un-assign yourself from a real DeployBlocker unless you are 100% sure someone else is assigned and will take care of it.
