| (basically something earthing out on sea water) or a single

| but minor points might only connect to the anchors and not each
| other).
|
| That said, Djibouti is a major cargo transport hub for
| Ethiopia, and is probably a network transport hub as well.
| Ethiopia is the 2nd most populated country in Africa and that
| would justify a lot of cable landings.

| sure of the specifics on modern DWDM cables. (they can run
| ~80-160 different frequencies of light on the same fiber, and

| Right now, everything is over satellite. Too bad the big

| I wonder how well protected they are specifically in the Suez
