As reported by Jasper Koehorst:
I was updating the biological databases in wikidata when I encountered cases where the official website was already added but did not show up on the SPARQL endpoint.
For example the following query:
Has no official website entry. However this entry was added by someone at 12:27, 20 May 2016.
As far as I can tell from previous experience the sync happens more or less spontaneously. However this is currently not the case. Is anyone aware of this issue?
Replication lag seems under control (around 10 seconds) so I expect that we have a few items missing replication and not a systematic issue.
