The crew of the ship for having dropped anchor presumably in defiance of 'Undersea cable, Do not anchor here' signs, or the telco for having sited a critical communications cable near/beneath a busy port ?

( Of course, I don't know the specifics, but if you have a choice, running your very-special undersea cable beneath a port would seem to be a bad idea )
...an alternative ISP would have made big bucks during those blockout days using some satellite gear, no? ;-)
subject to the availability of: uplink stations adequate bandwidth _to_ the uplink stations available satellites in 'line-of-sight' available transponder time on useable satellites. cost of that time. available 'downlink' earth receiving station(s) adequate bandwith connectins _from_ downlink points. cost of the downlink service Getting significant bandwidth on a satellite link, for any extended period, takes a *lot* of advance negotiation and arrangements.

Significant bandwidth is also quite relative term. One transponder can carry about 45Mbps maximum and a satellite has only a few dozen of them. It also gets quite expensive quite quickly. Carrying a gigabit across satellite is not feasible with technology available. Pete
