We had some slowness today, where after some temporary issue cluster ended up spending >50% of it's time working on Spanish wikipedia template. We nuked the template (es.wikipedia site was also turned off at some moment), so now it is all up and running.
The template was used for adding a single line of text, though it took 20 seconds to render. ;-)
We'll probably have to do something about that.
Cheers for now, Domas
