Analogy/Comparison

Imagine the internet is a vast system of roads, and BGP is like the traffic signs telling vehicles where to go. A routing leak is when a small road sign accidentally claims it leads to all major cities, causing massive traffic jams everywhere else.


Why It Matters

This issue shows how fragile the internet’s backbone is and why even small errors can take down many websites, affecting businesses and individuals who rely on online services. For example, during this outage, thousands of websites and online services became unreachable for over an hour, impacting everything from small blogs to major corporations.
