So we have @BroadbandSky @skytv down. We have @marksandspencer hacked and app down for orders. We have @o2 with mast down and no mobile signal. Everything comes to a standstill. There is no compensation, no apology. The bill will still be the same at the end of the month.2025

Hi @O2, no one in my postcode area in SE15 has had any signal since Friday at around 2pm. Have raised this twice and been told by your network detector 'the network is fine.' It clearly isn't. Assume a mast is down. Any ideas?

On very unpopular views,when I’m having down/depressing thoughts or ‘keep it down’’be humble‘’I’m in control of you’’you don’t matter’ oppressive thoughts or just plain(excuse the expression)islamic thoughts,I know my O2 sats are down or CO2 levels in room are high. Long COVID.
