Grafana 5 changed its URL scheme to include a unique ID for every dashboard, which makes their URLs stable across renames. For now, it will redirect old URLs to new ones, but this will probably change in a future release.
Non-exhaustive list of places that should be checked for grafana URLs to update:
- metawiki (done except for pages containing historical IRC logs)
- mediawiki.org
- wikitech
- puppet repo
