Three UK is down — live updates on the outage

Three mobile network in the UK is experiencing widespread disruption — leaving many customers unable to make voice calls. This was first flagged at 1:05pm GMT on Downdetector, and it’s extended to Smarty and ID Mobile, which are both running on the same network infrastructure.

Three UK has itself acknowledged the disruption, describing it as an issue affecting a limited portion of voice services. They reassured customers that data services and emergency 999 calls remain operational, while apologizing for the inconvenience and promising swift corrective measures.

But with well over 30,000 reports since the outage began, this is impacting the whole of the UK. Here’s all the latest updates on what is happening.

One of the more humorous points of this whole outage was that Three's network status checker was down too.

Good news though! It's live again and Three is also sharing a little more detail on some of the wider impact too. "This issue is impacting some of our self-service options."
