Table 5 - Comparing 2019 growth to 2020 growth. Within these two lists there are a small number of economies where IPv6 deployment in 2020 exceeded the 2019 levels. In most cases the deployment slowed down in 2020, with the exception of the Philippines, Saudi Arabia, Thailand, Colombia, Ecuador, Argentina and Sri Lanka in this list. We can further break this down into a month-by-month change across 2020, tracking the five largest national deployments, shown in Figure 10. India's growth occurred in the first half of the year, while China's effort took place in the third quarter. Overall, the most active months were April and September according to the measurement data. This is a major change from 2019, where June 2019 saw the highest growth in the number of users, shown in Figure 11, and the monthly growth rates were consistently double or triple the monthly growth rates seen across 2020. It is evident that the pandemic had an impact across the entirety of 2020.
