Статьи эти слишком древние. Есть где-то современные публикации на эту
же тему, не помню только где.
Если маленький TTL и несколько записей, то современные браузеры
попробуют следующую после небольшого таймаута. Сам проверял оперу,
файрфокс и ие6.
Если мониторить и удалить запись, то у всех клиентов с нормальным днс
все будет хорошо сразу, могут наткнуться только на этот небольшой
таймаут, но ошибки не увидят. А те, кому днс кэширует записи и
игнорирует TTL будут натыкаться на таймаут еще какое-то время, тоже
без ошибки.
А если упавший сервер еще и будет возвращать RST, то таймаут будет
очень маленький.
