For the conspiracy theorists O2 is currently suffering a massive mobile network outage in the UK [https://www.telegraph.co.uk/technology/2018/12/06/o2-network-customers-lose-access-4g-data/ https://www.telegraph.co.uk/technology/2018/12/06/o2-network...].

But someone on twitter is claiming the third party is not Huawei. [https://twitter.com/NicFildes/status/1070606845881008128 https://twitter.com/NicFildes/status/1070606845881008128]
