And whether the tunnelling was future-proofed, i.e. capable of having additional and replacement cables economically laid / drawn. And whether and when it was augmented, then replaced, by optical fibre. (Or whether, when fibre took over - early 1980s? - it was easier and cheaper to tunnel-and-lay anew). Hopefully these stories are being written, and published (and not just gifted to 'IT platforms').
