Like what? Is it an issue with specific services/providers? Or total internet bandwidth? Anyone know the bandwidth the submarine cables can handle in their current configuration?
What's the real bottleneck here?
What's the real bottleneck here?
If there is any slowdown, it is likely due to limitations in the last mile. Netflix isn't sending 4k video streams from California to everyone else in the world individually, assuming everything is working.
ISPs overselling their last mile bandwidth.
A modern submarine cable, like Google's new Dunant transantlantic cable, has 250 Tbps of bandwidth. For reference, the largest Internet Exchange in Europe, DE-CIX, just reported a new traffic record of 9 Tbps.
So, no, anything using fiber isn'ta bottleneck. You can fit all of DE-CIX traffic on a single strand of fiber with off the shelf gear.
