This page still talks about socket.io and Varnish, which we haven't used for years: https://treeherder.readthedocs.io/list_of_services.html This page talks about the objectstore which was removed two years ago: https://treeherder.readthedocs.io/dataload.html I believe these are what resulted in this on IRC in #ateam: 12:41 <mikeling> Hi, what's the meaning of objectstore in the treeherder

Commit pushed to master at https://github.com/mozilla/treeherder https://github.com/mozilla/treeherder/commit/6419d2b61c6a0a5e116bd9a4e6635049331f9ebb Bug 1421327 - Docs: Remove out of date/redundant pages (#3834) The architecture pages are significantly out of date and so have been removed until such time as new ones are created (this will be simpler once Buildbot/REST API support is removed later this year). In addition, the deployment page duplicated the UI installation page.
