Which Nusach Ashkenaz communities/shuls say in Mussaf Yom Kippur the Seder HaAvoda that starts with "Ata Konantah"?
The standard Seder haAvodah in Nusach Ashekenaz is the piyut Amitz Koach. In Nusach Sefaradim/Edot haMizrach, and in Nusach Sfard it is the piyut Ata Konantah. However, both the Artscroll Machzor and Daniel Goldschmidt's Machzor note that a minority of Nusach Ashkenaz communities switched to Ata Konantah (DG notes that this was a very late development). Which communities did or do follows such custom?
