Cisco Podcast Network

On this week’s episode, we cover a couple of significant application-layer outages at Github and WhatsApp that occurred over the past week. Then, Archana and I do a deep-dive into a network-related outage at Cloudflare that affected the availability of its popular DNS service for approximately 30 minutes. We'll share what we saw through our vantage points in the ThousandEyes platform, and you can read Cloudflare’s full explanation of the incident on their blog.

On this week’s episode, I am joined by Deepak Ravi from our Dublin technical sales engineering team to discuss a recent outage at Garmin. Garmin confirmed that it was a victim of a ransomware attack, which took down several of its services including its website functions, customer support, customer facing applications, and company communications. In this episode, we walk through what we observed in the ThousandEyes platform during the time of the attack, and what the impacts were on users attempting to access Garmin services.Were also joined by ThousandEyes’ CISO, Alexander Anoufriev, to talk about what ransomware attacks are, how they manifest and how organizations can protect themselves against future attacks.

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, Archana and I discuss a small number of outages that hit certain regions of the globe over the past week. This includes an outage that caused a midday disruption for people trying to connect to Reddit, a weekend DNS issue at Telstra, and a Cogent outage in EMEA and NA that had the signatures of a maintenance window. We also revisit Cloudflare’s root cause analysis concerning their recent DNS outage and answer some of the open-ended questions we had.

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.

The Internet held up reasonably well over the past week, all things considered. There were no major outages to report, which is a welcome repose for those impacted by the major outages the week prior. While it’s not an outage that occurred this past week, we did want to spend some time covering the recent Verizon Edgecast outage that occurred on August 21st. Watch this episode as we dive into this application-level outage to understand exactly what happened and who might have been impacted.

It was another quiet week on the Internet, so we wanted to spend some time answering your questions around some recent outages. Catch this episode as we discuss how you can understand the upstream relationships of the services you rely on to assess your risk profile. We also cover why SLAs fall short in protecting your business in the event of an outage, and why you need to proactively collaborate with your providers to solve issues faster.

On today’s episode, Angelique and I cover off on a couple outages that occurred over the past week. First, we discuss an application outage at Instagram that occurred on September 17th and lasted around 30 minutes. We also discuss a network outage on September 14th on the AWS backbone near Columbus, Ohio. This outage was a little more widespread, affecting nearly 100 interfaces and lasting around 30 minutes. Next, we dive into the upcoming bans on WeChat and TikTok, which have now been temporarily extended by a Federal judge, and then we walk through some of the network architecture differences between these two applications and how a potential shutdown could be enforced.

Cisco’s Chief Privacy Officer, Harvey Jang explains how he went from working in a huge law firm to pivoting to a career in data privacy, and how the pandemic has shown just how important it is to protect people’s information.
