According to Mori V'Rabi-WAITING IN BETWEEN MILK AND MEAT

 

According to Mori V'Rabi Harav Hagaon R. Shlomo Miller Shlita, Ashkenazi Yidden (Yekkis) whose Minhag is not to wait six hours after meat ( 3 hours- 1 hour )  may continue to do so only in such cities where they have an Ashkenaz (Yekki) Kehilah. In a city where no such Kehilah exist one must accept the חומרא המקום שהלך לשם (Minhag Hamakom) and wait six  hours after eating meat.
