Hello all,
it looks like the WMF-techs are moving wikidata to cluster s5 at the moment (without announcement of course). I'm quite sure that this will break our wikidata-replication; so after my sleep I will look how the situation will be and than probably re-import wikidata everywhere (wikidata is still quite small at the moment so that's still possible). So expect the wikidata replag to rise during the next hours.
Sincerely, DaB.
