Hi,
Another recent example of a statement that does not seem to have been
updated: one of the WDQS servers seems to think the population of
Denmark is 5, though this was fixed on 1st of June. The other has the
correct value, it seems.
It's hard to reproduce since only one of the servers has it. I got the
error on this query:
http://tinyurl.com/hnpxgyh (this is a variant of a
not-so-simple example query I just built: "German states, ordered by the
number of company headquarters per million inhabitants" [1]). For trying
it out, this query might be nicer:
SELECT ?population WHERE {
wd:Q35 wdt:P1082 ?population .
FILTER (?population < 200)
}
since you can change the "200" to trick the caching.
Cheers,
Markus

Side remark: using arithmetic operations on query results is a great way
to get even more misleading statistics out of Wikidata ;-) It does not
seem as if we have that feature yet in many example queries.
