Hi Gerard. Blazegraph is the name of the open-source
SPARQL engine
being used to provide the Wikidata SPARQL service.
So Blazegraph *is* available to all of us, at
https://query.wikidata.org/ , via both the query editor, and the
SPARQL API endpoint.
It's convenient to talk describe some issues with the SPARQL service
being "Blazegraph issues", if the issues appear to lie with the query
engine.
Other query engines that other people be running might be running
might have other specific issues, eg "Virtuoso issues". But it is
Blazegraph that the Discovery team and Wikidata have decided to go with.
The beauty of SPARQL is that you can use URLs to show query results (and
even query definitions). Ultimately, engine aside, there is massive
utility in openly sharing queries and then determining what might the
real problem.
Let's use open standards to work in as open a fashion as is possible.
