Hello all!
We are currently experiencing issues with the codfw WDQS cluster, with a
sharp drop in successful queries [1]. We suspect that the cluster is
overloaded by some expensive queries, but we are still tracking them down.
This should affect only traffic routed to the codfw cluster [2].
We will post an update as soon as we know more.
Good luck!
Guillaume
