Decline and Fall
The BBC has a report on a small island nation in the Pacific, Nauru, which has basically lost contact with the outside world:
Nauru's telephone system collapsed on 8 January amid political chaos, and since then the island has only been contactable when ships equipped with satellite telephones made stops there, the AFP news agency reported
Nauru once had the highest per capita income in the world. Then, phosphate mining collapsed, an attempt to provide off-shore banking turned into money laundering for the mob and a current effort at interning asylum seekers for Australia has collapsed:
Late last year, Australian immigration officials admitted that the asylum seekers, mainly Iraqis, had been running their own detention centre since officials abandoned the site following a riot.
It feels post-apocalyptic, this report of a tiny nation almost completely cut-off from the rest of the world and sinking deep into chaos. It can't happen here, in our world, right now. But it does.
