Connecting a Custom Domain with One Click — a Pipeline Built Around 'You Can't Speed Up DNS Propagation'
I built a feature to buy a domain and attach it to a blog. Bought four with the same code; all four failed differently. One cause: we ignored a wait we can't shorten (DNS propagation) and tried to do everything synchronously. Once we accepted that wait as a given, the pipeline settled into one synchronous stage plus two worker stages.
