Access and mirror
An alternative address does not prove authenticity by itself. Verify its source through a channel you already trust and check the address bar before signing in.
A mirror is useful only when its origin can be established independently. Save a confirmed support channel in advance, compare the address character by character and avoid sites asking for a separate access fee. An unavailable page may simply reflect regional restrictions.
