Internet & Exchange Stuff
The physical connectivity of the Internet is of great fascination to me. From Submarine Cables and Cable Landing Stations to fibre ducts running up and down the country between Exchanges and POPs.
Submarine Cables & Landing Stations
The Secrets of Cornwall by Mark Thomas.
This video started my interest in searching further for the hidden buildings and ducts that make up the Internet Backbone of the UK.
Watched this video several hundred times pausing and following Mark’s journey mapping the sites he visited. Also used a number of sources like Secret Bases and Internet Maps to map other interesting sites. Some sites were found by endlessly and painfully zooming and scrolling Google Maps !
I have made up several KML files locating each these sites and the route of the GTN and other fibre cables.
Cable landing stations come in various forms. Mainly industrial buildings but here is one on a housing estate hidden inside two houses. The inner walls and floors have been removed to house the fibre terminating equipment. The four large air con units outside give it away. The garage houses the backup generator.
Collected from a number of sources like Secret Bases and Internet Maps and some painfully located on Google Maps by endlessly zooming and scrolling !
Local Telephone Exchanges, Fibre Cables & Data Centres
SMBT Fenny Stratford Exchange / Bletchley (MK) – bRAS
BT Wholesale has ten 20/21CN bRAS which are located at Birmingham, Bletchley (MK), Ealing, Edinburgh, Ilford, Kingston, Manchester, Reading, Sheffield, Faraday. If your ISP uses BT Wholesale for routing then you can be sure that all your traffic will have passed through one of the above bRAS locations.
There are a large number of network companies present at this site as indicated by the network chamber covers outside in the street.
Grass Area 1/2 mile from Fenny Exchange / Bletchley (MK) bRAS near Bletchley Tesco roundabout.
A number of fibre cables from the Exchange and bRAS start to run North from this small grass area just down the road towards the Centre MK and SMBA Bradwell Abbey Exchange.
A fibre cable running to the Bank of England runs under one of these network chamber covers using dark fibre provided by Zayo (formerly Geo). 186k was taken over by Geo Networks and further by Zayo, so it’s most likely under those 186k covers.
