Heard similar...
I was told a similar story by an ex network-op of mine - as I recall (and feel free to correct me if I'm wrong) but it was something silly like Ghana (or at least, the state I was told about) having a very small netblock allocation as a country, or only having a single gateway in, or the whole lot being proxied through one server, or other similar 'brick wall' hard limit connectivity problem that up until then, hadn't been a problem.
Then 'something' occured that made their IP range get flagged up, the whole internet went down for the country.
I think the story I was told was about a Gulf state (Jordan? Qatar?) but it's apocryphal anyway, so it might be the same tale.
Anyway, reminiscence over, back to work, sigh.
