I heard in this case, both Proximus and Telenet, the main operators in Belgium, run their fibers in the same conduit. So every company thought they were redundant by buing both, but weren't. I also heard the railways are the main fiber provider: They have long stretches of rail between all major cities, so they are ideal for fiber. But very bad for redundancy
