In route one circuit from Washington to London via ashburn and down to Texas before going on subsea circuits through mainland Europe to ensure path diversity. The other heads north east towards Newark and and surfaces in Bude. That took two years of contractural arguments.

Fibres on the Texas link die all the time (yearly) but that’s fine.

My circuits in the far east are often carried one via dues and one via the USA.

It is possible to guarentee diversity, you just need to get specific detail and have good contractual protections.
