    ouch...im hoping they can pinpoint where the exact fault is....cos if theyve gotta examine the cable inch by inch.... !

    Re: 24,500 mile long cable breaks, disrupting Internet for millions

    I wonder if they have certain points, like boosters or relays or something every so often (like every 10 miles or something), or if it is indeed one very long cable?
    Does anyone know how many undersea cables like this there, and how much fault tolerance we have? Obviously we haven't lost our conection to Australia & Japan so there are other cables.

    Re: 24,500 mile long cable breaks, disrupting Internet for millions

    With fiber cables, any break in the cable can be found by bouncing light through it and seeing how long it takes to come back. Then by deviding by two and knowing the speed of light in glass you can work out how far along the cable the break is.

    Actually, I think you can do something similar with copper, but i don't know how that one works. Something to do with atenuation or something.

    Suffice to say, they don't have to check every inch

    There have to be relays. It is not possible to send stuff down a 24,500 mile cable (whatever type it is) in one go.

    I dread to think how much a 24.5k mile cable costs

    I think i saw Maplins doing a deal on nearly that much in town. Maybe someone should tell the middle east?
