摘要

COVID-19迫使许多国家的居民选择或被授权在原地避难。因此,互联网的使用激增,给固定和移动宽带网络都带来了压力。在这个公告中,我对宽带网络在下载速度方面的表现进行了初步的了解。利用2020年3月前后几个月固定和移动网络的每周速度数据,我发现一些国家的速度大幅下降,但也有一些速度上升。更大的负面影响在低收入国家和网络速度较慢的国家更为常见,只有法国等少数国家例外。值得注意的是,美国的固定网络对流量激增具有弹性;下载速度没有统计学上的显著变化。另一方面,美国的移动网络在下载速度上有统计学意义上的显著提高。

COVID-19 and Broadband Speeds: A Multi-Country Analysis
COVID-19 has forced the residents of many nations to shelter-in-place, either by choice or by mandate. As a result, Internet use has skyrocketed, putting stress on both fixed and mobile broadband networks. In this BULLETIN, I take an early look at the performance of broadband networks with respect to download speeds. Using weekly speed data for fixed and mobile networks for months preceding and following March 2020, I find sizable reductions in speed for several countries, but also some increases in speed. Larger negative effects appear more often for lower-income countries and those with slower networks, with a few exceptions including France. Significantly, fixed networks in the United States were resilient to the traffic surges; there were no statistically-significant changes in download speeds. Mobile networks in the United States, alternately, were found to have a statistically-significant increase in download speeds.
