Re: Undersea fiber cut after Taiwan earthquake - PCCW / Singtel / KT e tc connectivity disrupted

That's news?

The same still happens with much land-based sonet, where "diverse paths"
still share the same entrance to a given facility.  Unless each end can
negotiate cost sharing for diverse paths, or unless the owner of the fiber
can cost justify the same, chances are you're not going to see the ideal.

Money will always speak louder than idealism.

Undersea paths complicate this even further.

most cost effective solution. However, that means that diversifying across undersea cables does not buy the sort of 
physical diversity that is anticipated.
