I've noticed today that migrated questions now redirect immediately to the target site. Previously, I had enough rep that the original question was still visible on the original site without an automatic redirect. Has this changed?
This is by design -- we feel a migrated question should take you directly to the destination, since otherwise it's just another click to get to the actual question and any answers.
There's a link on the destination site that sends you back to the closed version of question on the original site. It passes
?noredirect=1 querystring to force not to redirect.
