Hours may vary considerably depending on the preference of the individual businessperson. Business appointments are rarely made before 10 am. The telephone system in Baku is oversubscribed and technically inadequate.
International calls are possible, but expensive.
E-mail via local Internet providers is available. Full Internet service has also recently become available. The GOAZ postal system is functional, but not secure. There is a functioning subway system in Baku, but, because of severe maintenance problems, the U.S. Embassy discourages Americans from using it. Buses and streetcars run, but are crowded and not recommended.
