Speculation on the net is US Dem Kerry etcetera applied pressure while visiting London and elsewhere. Assange is effective Ecuador citizen, not sovereign Ecuador state employee, thus E is censoring its citizens independant journalism (though presumably only from formerly using state resources to do so). Wifi / cellular / broadband subscription is surely available or provided in area (by supporters or party vans). WL is presumably operationally insulated.
