Re: [Wikitech-l] Setting up multiple Parsoid servers behind load balancer

Hi, This sounds like a lot of sublayers that can potentially disrupt a simple editing process and I wonder from the many non-WMF MediaWiki installations and administrators, who will be able and capable to debug those once an issue arise. MediaWiki-core itself isn't a walk in a park and now and then you find a bug that is addressed post six month, left alone for a year, or worse never see a response. Now, I can imagine that those added layers don't necessarily make this process easier and the current response times on phabricator make me skeptic about the outlined requirements and hereby the added complexity.
