Hello!

Starting at 7pm UTC I will activate HTTPS on our elasticsearch cluster [1]. This is only preliminary work to actually enable encryption, the clients (mediawiki) will not be reconfigured until we have fully tested this deployment.

This is part of the preliminary work for the eqiad -> codfw datacenter switch.

Again, this should have no impact, but I have been known to be wrong before. If you see strange behaviour around search, please let me know...

Guillaume
