his is the Internet Report, where we uncover what’s working and what’s breaking on the Internet—and why. On this week’s episode, Archana and I cover some recent outages that made headlines. This includes the Spotify outage, caused by an expired TLS certificate, that prevented users from accessing its platform. We also cover off on a widespread outage at Cogent during (what seems to be) a maintenance window. Then, we go “under the hood” on the prolonged outage at an IXP on August 18th to understand exactly what infrastructure was impacted and which downstream providers were subsequently impacted. We’re also joined by our guest, Prabhnit Singh, who currently leads ThousandEyes’ Internet & WAN product line, to discuss why we’re seeing an increased number of outages caused by expired TLS certificates and to cover some examples of past high-profile outages.
