KT built fiber connection here in Poland ~15y ago. Project was made in a large part of the country, strongly subsidised and thought as a backbone for other ISPs. 4k km of fiber underground and multiple nodes.
Project is now being nationalised as kt:
- didn't pay subcontractors. Many of them went bankrupt
- offered prices so large, that other isps would rather create their own infra than use theirs
- abandon the project totally
Of course i shouldn't put this under KT's name, as they used a subcompany - SungGwang - for all the dirty stuff.
So, fast forward: we laid a new infra parallel to this one in many cases and that one lays in the ground and rots.
