As typical L2 technology for such cables is SDH/SONET, the difference in latency after single ring failure tends to not be noticeable for normal IP traffic.

- runeks 12y agoInteresting. Can you expand on this? How is that possible? If we take the TAT-14 example again: https://en.wikipedia.org/wiki/TAT-14#mediaviewer/File:Map_TAT-14.png https://en.wikipedia.org/wiki/TAT-14#mediaviewer/File:Map_TA... How will the ping times not increase dramatically from Bude (UK) to Saint-Valery-en-Caux (FR) if the connection between them breaks?
- mikeyouse 12y agoThe total length of the cable is 'only' 15,428km. So the maximum one-way latency between any two points is only ~70ms assuming 0.7C. You'd definitely notice if you were gaming, but probably not if you were watching YouTube.
