Explanations for VPN trend peaks in Austria:
1. Peak from 2020-03-15 to 2020-03-21: VPN searches in Austria were likely unusually popular during that time due to the start of COVID-19 lockdown measures. As people began working from home and spending more time online, the need for secure internet connections increased. Additionally, there might have been increased interest in accessing restricted content or services not available in Austria, leading to a spike in VPN searches.
