This is the Internet Report, where we uncover what’s working and what’s breaking on the Internet—and why. On this week’s episode, we cover a widespread T-Mobile outage that took down its cellular network for several hours and elicited a rare condemnation from the FCC. The culprit, according to the carrier, was a fiber cut—highlighting the need for redundancy and resiliency in the nation’s cellular networks. We also cover an issue with What’s App’s privacy settings that sent users scrambling to Twitter, as well as a recent move by Russia to “un-ban” the messenger app, Telegram. Then, stay tuned as we go one-on-one with Jason Black, the Head of Global Network Infrastructure at Uber Technologies, to discuss how Uber approaches its cloud architecture.
