They have not even bothered to implement entra login when they have their competitors login for years, do they even know what their product is? Or are you just a middle man for slop?
Might catch 90% of problems before they make it into the real stack?
E.g. every step of GitHub's migration to Azure could be mimicked on the duplicate stack before it's implemented on the primary stack. Is this just considered too much work? (I doubt cost would be the issue, because even if it costs millions, it would pay for itself in reduced reputational damage from outages).
EDIT: downvotes - why? - I think this is a good idea (I'd do it for my sites if outages were an issue).
If you'd ever worked on a codebase as terrible as I imagine GH's internals are and looked at the git history, you'd find two things:
1) fixing it would require rolling back 100's-1000's of engineer-years of idiocy that make things like testing or refactoring untenable
2) many prior engineers got part of the way through such improvements before leaving or being kicked out. Their efforts mostly just made it worse, because now you never know what sort of terribleness to expect when you open an unfamiliar file.
Because that's a monumental amount of work, and extraordinarily difficult to retrofit into a system that wasn't initially designed that way. Not to mention the unstated requirement of mirroring traffic to actually exercise that system (given the tendency of bugs to not show up until something actually uses the system).
Agree, but look at the alternative; GitHub is constantly being savaged by users who (quite reasonably) expect uptime. Ignoring impacts on morale and reputation, damage to their bottom line alone might tens (hundreds?) of millions per year.

yeah, I agree that's difficult, but it need to not be exact to still be useful.
