Hello, As mentioned, we ran into issues with the cookbook due to a typo, which has been fixed <https://gerrit.wikimedia.org/r/c/operations/cookbooks/+/1193860> . We plan to try again on Thursday, 12:00 UTC.
The item has been added to the deployment calendar: https://wikitech.wikimedia.org/wiki/Deployments#deploycal-item-20251009T1200 Thank you for your patience.
