Akamai's State of the Internet Q4 2015 Summary

Core Content Overview

Akamai's Q4 2015 State of the Internet Report provides insights into global and regional Internet connection speeds, broadband adoption, IPv6 adoption, and mobile connectivity trends. The report also highlights IPv4 exhaustion and Internet disruptions observed during the quarter.

Main Goals and Updates

• Report Evolution: The report has evolved over the years, with a shift in focus from general Internet metrics to more detailed security-related content in a separate report.
• Future Enhancements: Akamai plans to include IPv6 connection speed metrics and shift from using average connection speed as the primary metric to a more representative one starting in Q1 2016.
• Mobile Data Return: Mobile connection speed and browser usage data have been reintroduced, with improved identification algorithms, covering ten more countries than previously.
• Report Accessibility: The report is now available for download on e-readers and tablets, with links at stateoftheinternet.com.
