The COVID-19 pandemic dramatically changed the way of living of billions of people in a very short time frame. In this paper, we evaluate the impact on the Internet latency caused by the increased amount of human activities that are carried out on-line. The study focuses on Italy, which experienced significant restrictions imposed by local authorities, but results about Spain, France, Germany, Sweden, and the whole of Europe are also included. The analysis of a large set of measurements shows that the impact on the network can be significant, especially in terms of increased variability of latency. In Italy we observed that the standard deviation of the average additional delay – the additional time with respect to the minimum delay of the paths in the region – during lockdown is times as much as the value before the pandemic. Similarly, in Italy, packet loss is times as much as before the pandemic. The impact is not negligible also for the other countries and for the whole of Europe, but with different levels and distinct patterns.

COVID-19 大流行对互联网延迟的影响：一项大规模研究
COVID-19 大流行在很短的时间内极大地改变了数十亿人的生活方式。在本文中，我们评估了在线进行的人类活动量增加对互联网延迟的影响。该研究重点关注意大利，该国经历了地方当局施加的重大限制，但也包括西班牙、法国、德国、瑞典和整个欧洲的研究结果。对大量测量结果的分析表明，对网络的影响可能很大，特别是在延迟可变性增加方面。在意大利，我们观察到，封锁期间平均附加延迟（该地区路径最小延迟的附加时间）的标准差为是大流行前的价值的几倍。同样，在意大利，丢包率是是疫情前的几倍。对于其他国家和整个欧洲来说，影响也不容忽视，但程度不同，模式不同。
