I was testing some code late at night in the test system. Rolled out the changes, log on to the admin interface and write a short news article about how one of the more hated profs at the university had died suddenly and unexpectedly.
Result looks good, roll out changes to prod, about to call it quits for the night. Think to myself: common reason people get fired, maybe delete the story from test system. Check test system, no story there… Uhoh.
Story has been live for about three hours. Hope no spiders have caught it yet, hurry to delete it and learn how to purge all evidence from database.
Turns out the shithead admin had copy and pasted the server config for the test system from live and forgotten to change the admin rewrite rules to test system. Phew…
