Overview
- Ofcom said the probes will establish the facts and assess any breaches of obligations that require operators to take appropriate, proportionate measures to ensure service availability and mitigation.
- BT reported a software fault on July 24–25 affecting its EE network that left many customers unable to make or receive calls, including to emergency services.
- Three reported a separate failure on June 25 that impeded access to 999, citing an exceptional traffic spike triggered by a third‑party software configuration change.
- The new actions follow an earlier Ofcom investigation opened in June into BT after technical faults affected the 999 emergency call service.
- BT pledged full cooperation and issued an apology for the disruption, while Three said compensation would be handled case by case and BT/EE have not confirmed any payments.
