Починился Mikrotik
Около полугода юзаю DoH на роутере Mikrotik. Разные DoH. Все они в последнее время выпадают в ошибки. Меняю вручную на разные от самых известных, до экзотических малоизвестных. Роутер этот для сильно второстепенной сети, отвалы некритичны. Провайдер один из самых больших, белый IP. Ухожу на выходные, на выходных происходит инцидент, в логах вижу следующее (удалил десятки одинаковых сообщений об ошибках коннекта, тут интересна хрогология :) и ошибок DoH больше нет, пока нет):

Просто пример как инцидент не у провайдера вылечил отвалы DoH. Важного тут ничего нет.
В тэгах не шарю.
