Hi!
I've finished migrating SPARQL examples to https://www.wikidata.org/wiki/Wikidata:SPARQL_query_service/queries/examples - this is now the official examples page.
I've also created a redirect: https://www.wikidata.org/wiki/Wikidata:SPARQL_examples for convenience. The old page at mediawiki.org is now soft redirect to a new one.
Please notify me if you see any issues.
Thanks,
