When 25 Broadway failed, approximately 1% of the global Internet
routing  table also disappeared.  Which I would guess qualifies it
as a "major" hub.

Verizon still has 100,000 lines out of service, and only now
begun to restore service to "small" businesses.

A couple of years ago a fiber cut in Ohio disrupted about 20% of
the Internet routing table.
