I don't understand how a redirect could happen.

ServiceWorker.ContextRequestHandlerStatus.InstalledWorker.ImportedScript
ServiceWorker.ContextRequestHandlerStatus.InstalledWorker.MainScript
ServiceWorker.ContextRequestHandlerStatus.NewWorker.MainScript

sometimes have the redirect error (less than 0.00% of the time).

Maybe captive portals?

The impact to the user is that the service worker will just fail to load.

Spun off of  Issue 485900 .
