Apologies for top posting but my handheld doesn't do quoting.
There will always be large peering points in networks but the telecoms side of things generally has a bit more redundancy to it than the is seen directly,
At work we've got dual feeds into UUNet no MCI no thats not right now either, ahh Verizon Business' network routed via crawley to mci at Reading and via Croydon to MCI in London.
Of course we pay grandly for this but so do BT for the Colossus ATM nettwork through which all your DSL traffic (For non LLU customers at least) travels before branching out to your ISP's network.
This allows BT to dynamically route traffic to different endpoints dependant on what information the ISP's Radius server provides.
So yes Docklands as a whole is a pretty large weakness if targetted as a whole, but then there are much larger issues at stake if an event of such magnitude as can destroy the docklands area takes place!

Hello,
I moved from dial-up to broadband a couple of years ago, and discovered
that I was connected via a new facility away from central London. This week
my connection was apparently moved to Docklands, and I started to wonder
whether we are placing too many of our eggs in a single area of Docklands.
The BT network always used to be decentralised by design, but do we now
depend too much on a single convenient data exchange for what is now a vital
facility?
