We generally try to avoid deploying after friday morning here.
This allows us for at least 4 to 5 hours to switch back to an older / stable tag, or fix it if we see it's a small problem.
Having a good deployment strategy also helps, because you can quickly roll back to a stable version.
That, and testing your releases as good as possible.
