 Virgin Media has apologised after a network outage left thousands of customers without internet access in London for six hours on Thursday, enraging people forced to work from home because of lockdown. Britains broadband and mobile networks have largely held up well despite the huge strain of millions of people working and streaming video games and movies from home during the day. Regulator Ofcom said in May that average broadband speeds had fallen only 2 per cent during lockdown despite daytime traffic rising between 35 per cent and 60 per cent.
