The changes in usage patterns have resulted in corresponding changes in network traffic demands observed by Internet service providers. Although there have been several preliminary measurements of the effects of the COVID-19 response, none have holistically studied traffic data, performance analysis, routing data, and ISP capacity information together, as we do in this paper. We focus on the capacity changes during lockdown by inspecting two data sources: (1) to understand how ISPs responded by adding capacity to interconnects, we study the interconnect capacity of two large ISPs in the United States; and (2) to understand how video service providers expanded their network footprints in response to increasing demand, we analyze IPv4 address space from two major video conference providers-WebEx and Zoom-and find that both providers substantially increased advertised IP address space.	./cache/cord-170666-zjwlmzj3.txt	./txt/cord-170666-zjwlmzj3.txt
