We've recently run on a single server for couple of days due to reloading of the second one, so this may have made it a bit slower. But that should be gone now, we're back to two.

But if we see somebody making serious negative impact on the service, we may have to change that. -- Stas Malyshev smalys...@wikimedia.org _______________________________________________ Wikidata mailing list Wikidata@lists.wikimedia.org https://lists.wikimedia.org/mailman/listinfo/wikidata
