The English Channel: The Most Reliable Way Across Is The Chunnel

Many networks have Paris and London POPs. Unfortunately,  the English Channel is teeming with cargo and fishing vessels. So subsea cable outages are common and made worse by the fact that only three new subsea cable has been built in the last 20 years, Scylla, Zeus, and CrossChannel. Most of the older cables are more susceptible to outages because undersea surveys and burial standards have sharply improved in the last 15 years.

 In contrast, the Chunnel consists of two railroad tunnels plus a service tunnel carved out of solid rock, mostly chalk, approximately 75 meters below the sea floor and protected from sea water by a layer of clay. Fibre has been installed in these tunnels and several long haul providers offer the route at prices comparable to those on subsea cables. This is undoubtedly the most reliable route between the two countries and I highly recommend it as part of any network linking the UK to the European Continent.
