Amazon Builds First Solo Subsea Cable Linking Maryland To Ireland (aboutamazon.com) 34

AWS today announced Fastnet, a subsea fiber-optic cable that will link Maryland's Eastern Shore to County Cork, Ireland. The project marks Amazon's first wholly-owned subsea cable system after previously participating in similar ventures through consortiums.

The cable will carry data at speeds exceeding 320 terabits per second. Amazon did not disclose construction costs but expects the system to begin operations in 2028. The company is burying the cable roughly one and a half meters deep across the ocean floor. Installers will bore a horizontal tunnel from shore to shore. Amazon has added protective steel wiring to guard against ship anchors and deliberate sabotage.

    Sad to say but these days that is a real possibility.

    Why do we, a supposedly intelligent species, make war rather than cooperate ? If you think that I am naive - please explain.

      Because some members of our species have not evolved sufficiently to understand what "enough" looks like.

      It's the same mental disease that creates billionaires who already have more material wealth than ten generations of their progeny could ever spend, and yet they still have the drive to literally starve children in order to get tax breaks they don't need to aide in accumulating more wealth they don't need.

    Where in the source article does it say anything about "burying the cable roughly one and a half meters deep" or "bore a horizontal tunnel"?! If they were going to bury this, surely they would trench, not bore. And it's not clear they are burying it at all. The infographic seems to show it on the surface of the ocean floor. And it shows that the cable is one and a half INCHES THICK, not meters deep. SMDH.

    • Post on Slashdot seems poorly done, almost voice dictation. Who writes "one hundred and $44 million" instead of "$144 million"?

      AWS has become a high-value target for sabotage by foreign governments or major competitors, as we saw a few days ago an interruption in AWS services shuts down large swaths of our government and much of our corporate activity. I could easily imagine Ellison paying someone to cut AWS's cable to promote Oracle's pitiful excuse for cloud services.

      • Or more reasonably: Russia or China "accidentally" dropping / dragging an anchor across it's path and crippling the US Government cloud-based operations for weeks by fucking over their prime cloud contractor.

          I'm quite sure that most of the really major cables are already mined so they can be destroyed in an instant (or threatened to be destroyed) in the case of open hostilities. The major maritime powers would be foolish not to, they're much too valuable an asset to an opponent's military to not take them into account and it takes too much time to move ships into position to do it if a hot war erupts.

  • I strongly suspect an error in the summary. I donâ(TM)t think itâ(TM)s technologically possible to horizontally bore a fiber conduit 1.5 meters deep across the entire Atlantic Ocean. Someone please explain whatâ(TM)s actually happening here.

      Yeah that sounds off. Probably mean digging at coastal shallower waters then just having it lay on the floor elsewhere, that's the standard.

      • by cusco ( 717999 )

        They mention it because they're not following the standard practice, they appear to intend to bury the entire cable rather than just the near-shore portions. Considering that AWS is now a major component of the US economy and supports huge swaths of the US government it's probably a good idea to protect it from sabotage, cables are easy and tempting targets.

    • by cusco ( 717999 )

      I'm sure they're going to trench and bury the cable, modern journalists are mostly scions of the wealthy families who have never worked in the real world so have no clue that "bore" and "trench" don't mean the same thing.
