After sufficient CYA steps are taken, don’t offer any help on this problem unless explicitly asked to do so. And even then wait until there’s actually desperation. Feel free to think about it so you have some ideas when the time comes, but if this service isn’t something you are responsible for then stay away.

Or else it will be a “you touched it last you broke it” regardless of what actually happened. And if you make too much ruckus about it, they’ll say “why didn’t you do anything to fix it??”
