Is there a big problem with the SPARQL servers ?

I was just about to update some of the numbers at
which has the numbers for sitelinks, cross-properties etc for painters
with P1367 (Art UK artist ID; formerly "Your Paintings" artist ID).

SPARQL used to return 22,412 hits; and Autolist currently returns 22,458
hits (the latter includes deprecated values).

But now SPARQL is only returning 18,291 hits

What's going on?

The number has been over 22,000 since at least October last year.  (And
before that was down at about 8,700).

Should all SPARQL searches be currently seen as unreliable ?

Should there be a warning on the search page advising of this ?

Yes unfortunately there are some hickups currently. See this email by Stas: https://lists.wikimedia.org/pipermail/wikidata/2016-April/008618.html
