USPS unilaterally cut off the tracking of all registered international parcels on the territory of the United States.                                                                                                                                                                                   Tracking stopped for a list of countries, including Russia. Disabling occurred on the night from 16 October to 17 October 2015.

Shipping 20 - 65 days.
Usually delivery takes 30 days or less, but sometimes there are delays not the fault of Russian post.
