BCC doesn't have a staging environment, owing largely to being cobbled together with bubblegum from back when HTML written in Notepad was cutting edge web technology for me. I also use a lot less testing than is considered ideal in the Rails community. Getting a staging environment is probably worth doing, but the level of coverage with Selenium tests I would need to catch things as obscure as "had an image delivered over HTTP on the landing page" strikes me as not likely to have the highest ROI of all things I could be doing.
(I've been interviewed about what I do for reliability before. The short version is checklists and automated warnings when stuff goes wrong. I've set up some automated things to catch issues spiritually similar to the ones described in this post already.)
