The pipe dreams of Tech City entrepreneurs
So who is right in the battle for broadband? BT, which proclaims that London is the No.1 choice for businesses because of its high levels of connectivity (tethered to a multi-billion rolling upgrade in infrastructure).
Or the entrepreneurs working at the silicon-face of the east London Tech City dream.
Their champions, such as Tech Hub's Mike Butcher, have amassed considerable evidence of foot-dragging by the "monopolistic" BT, which holds the whip hand.
Mr Butcher, and others, quote the data that puts the capital outside the top 30 performing cities in a winner-takes-all global beauty contest.
Chairman of the London Assembly economy committee Andrew Dismore said: "London's broadband is becoming the 21st century equivalent of tin cans on a string. There is no doubt that this is having a detrimental effect on the capital's competitiveness and is hampering both old and new businesses, as well as many residents."
Poor infrastructure, sluggish service, the Catch 22 of start-ups which cannot order a link until they rent an office and cannot rent an office without revenue and cannot earn revenue without a link.
This is the sorry story for many start-ups, we are told - green shoots of hope trampled by the tractor-factory mentality of the monolith.
(BT, for its part, says the average turnaround for an order is seven working days, says anecdotes are no basis for policy and proffers other independent surveys putting the capital as a business leader in this arena.)
Either way, the argument is connectivity and it is, ironically, beset with problems of joined-up thinking.
This argument, going in circles much like Shoreditch's famous roundabout, is costing status. As Mr Butcher and other provides told the London Assembly last week, Berlin is white-hot, gigabit links are commonplace in Seoul and little Moldova offers free wifi.
London is an elephants in fishnets - desirable but unwieldy.
When an industry scans the world for a place to stick its start-up, London has many advantages - but insists on making its entrepreneurs suffer for their decision.
As the Olympics quickly fades and business gets back to normal, this will become an issue of greater importance. As seems likely, iCity will take over the Olympic Park media centre, stretching the boundary of Tech City further east, which is welcome.
Meanwhile, the Royal Docks has the potential to become a sci-tech campus of considerable heft.
The very least that these two centres will require is the latest in ultra-fast connectivity with the most robust pipes, the broadest bandwidth, free wifi and all the trappings of a modern, fleet-of-foot Singapore-style start-up environment underpinned with a clean-driven, always-on, service-with-a-smile coffee shop culture.
It is likely that a mixture of dull-but-necessary pump priming public money (enterprise zones, transport infrastructure, wholly reformed education etc) and private capital is the only way to create critical mass.
(It is interesting to note the virtuous "arms race" between infrastructure and entrepreneurialism in places like South Korea where big pipes have helped create a large gaming industry and vice versa.)
All this feeds directly into the undisputed (by the main political parties) route out of the current malaise and provides a template for growth for our little, offshore island fighting for traction in a post-finance world.
What happens in east London in the next few years will be the measure of what happens to Britain.
High growth, geographically promiscuous players drawn here by the fast-moving, holistic, immediate sci-tech and digital economy able to draw skilled young people from a driven education sector. Or dead docks.
