The best solution is to create own url shortening service, that way we can reserve our  domain.

The idea:

Suppose we have a table with following columns:
* unique auto increment id (long),
* url (string),
* base62 string (string)

The trick, convert unique id to base62 string not the url, and then the url is mapped to the unique id
