I spent nearly three days debugging a configuration issue that I resolved by simply deleting the wonky Azure App Service and rebuilding it from the CI pipeline. It's hard to find a real-world analogy. The total time required to simply start over (given the automation we've spent two years building) was less than an hour, meaning had I done that Thursday morning, instead of trying to fix the unfixable problem, I'd have saved myself a net 22 hours of grief.
