Krinkle added a comment. @Magnus It is well-known currently that MediaWiki exposes many powerful API that we do not support to perform well, but allow regardless as a convenience service. If we were stricter about response times for all features, we'd probably just turn many of them off and

jcrespo added a comment. > since yesterday Could you try again? There was a regression on .10 that now has been reverted, and the timing matches the .10 deployment to wikidata. This is still a bug if it no longer happens, and we need to notify so it doesn't reappear (we are now on 0.8
