Telephone faults are problems with the telephone line which prevent communication. This map shows where people are most likely to find telephone faults. Some telephone lines serve an entire village, a fault on the line affects many more people than if the line is for one household.
Telephone faults have a different distribution to telephone lines: Southern Asia has 19% of all telephone lines, but 58% of all telephone faults. People with worse access to telephones often also have a less reliable service. It is also likely that the length of time taken to correct faults is similarly distributed, but data on this is not easily obtained.
