1.  We've started setting Cirrus as the primary search backend for wikis again.  Cirrus and Elasticsearch are holding up - and I don't believe we have any horrible bugs at this point.  Is everything looking good on your side?  Here is the schedule (from https://www.mediawiki.org/wiki/Search#Wikis):
