Добрый день!

На днях мне прилетели реферальные бонусы (аж 25$, еее!) и я заглянул в свой аккаунт на DO. Недавно они серьезно перепилили свою панельку и теперь она выглядит “более энтерпрайзно”, но данный пост не об этом. Меня привлекла новая локаци в Бангалоре. Мне нравятся такие вот экзотические вещи. Поэтому я просто развернул виртуалку на минимальном тарифе в данной локации и провел замеры. Результаты публикую сюда.

SpeedTest

Видимо из-за ip из американской подсети speedtest неверно определил местоположение сервера и протесил скорость до сервера в штате Огайо. Естественно результаты получились вообще никакие.

Выводы

Было бы интереснее если бы ip-адрес определялся как индийский. В остальном все вполне нормально. Стоимость виртуалок тоже неплохая.
