Verizon Outage: The End of Five-Nine Network Reliability

Last week's Verizon outage, which left millions of customers without service for nearly eight hours, has raised concerns about the reliability of software-based networks. This incident may signal the end of the five-nines reliability standard that has been a benchmark for network uptime for decades.

Impact on Verizon Subscribers

Roger Entner, founder and analyst at Recon Analytics, estimated that the outage affected 1.5 million Verizon subscribers. Many experts believe that a software update on the 5G standalone core caused the issue, highlighting the potential vulnerabilities of software-based networks.

The Shift to Software-Based Networks

With the modern 5G Standalone networks, the core is virtualized and cloud-native. While this allows for quick changes through software updates/patches, it also increases the risk of a single line of bad code taking the entire network down.

Reliability Standards in Question

Five-nine reliability, which guarantees a network is available 99.999% of the time, is no longer achievable according to Sanjoy Paul, a researcher who has helped build 2G, 3G, and 4G networks. With carriers moving to a software-based provisioning system, reliability drops to three-nines (99.9%), resulting in more downtime.

Implications for North East India and Beyond

The shift towards software-based networks is a global trend, and the Verizon outage serves as a cautionary tale for telecom providers in India, including those in the North East region. As networks become more complex, the risk of outages increases, and providers must prioritize network resilience and redundancy to maintain customer satisfaction.

Reflections and Future Considerations

The Verizon outage underscores the importance of network reliability in an increasingly connected world. As networks evolve, providers must strike a balance between innovation and stability to ensure uninterrupted service for their customers. This incident serves as a reminder that network outages can have significant consequences, and proactive measures must be taken to mitigate their impact.
