I am trying to access the URL https://www.wikidata.org/wiki/Q18289639?action=constraintsrdf&nocache=1531160117052 on production host (wdq1009.eqiad.wmnet) and I am getting this:

I've hidden the IP just in case, ping me for it if needed. This is strange since other accesses to Q18289639 work, and action=constraintsrdf is not even an editing action, let alone why WMF production host is being blocked?
The IP seems to be that of webproxy.eqiad.wmnet (which wdq9 is using as proxy).
