T-Mobile President of Technology Neville Ray revealed his 2020 playbook during the Wells Fargo Virtual 5G Forum on Thursday. But first, he had to explain what happened on Monday, when the operator experienced an hours-long service outage.
Most of the problems had to do with VoLTE calling, triggered by a fiber outage in the Southeast. A series of events followed to compound the situation. Ray earlier explained in a blog post that T-Mobile worked with its IP Multimedia Subsystem (IMS) and IP vendors to add permanent additional safeguards to prevent it from happening again.
