Rookie question: Are there parts of the world that don't have IFR service
such as Africa and Siberia etc?


Assuming by "IFR service" you mean separation of IFR aircraft by air traffic
control, yes. There are parts of the US that lack that service.



If so, what does one do if you must fly and
IFR conditions prevail?


You hope nobody else is doing it at the same place and time you are.
