There would be no TL;DR in this article, sorry.
Those have been three months that genuinely changed the world. An entire lifeline passed from February, 1, when the coronavirus pandemics just started to spread outside of China and European countries were about to react, to April, 30, when nations were locked down in quarantine measures almost all over the entire world. We want to take a look at the repercussions, cyclic nature of the reaction and, of course, provide DDoS attacks and BGP incidents overview on a timeframe of three months.
In general, there seems to be an objective pattern in almost every country’s shift into the quarantine lockdown.
On April 23, 2020, an AS205310 leaked routes from one of its upstreams to another (from AS8220 to AS15943), affecting 90 000 prefixes.
In some cases, such an incident could lead to massive network degradation across dozens of ISPs. However, it did not. Why?
Because some companies install and maintain their filters properly. And even taking into regard the fact that AS15943 is directly connected to Tier-1 ISPs, they didn’t even notice the incorrect routes. They simply never reached Tier-1s, shrinking in size after each hop.
