On this episode of The Internet Report, we discuss a large-scale route leak that briefly altered traffic patterns across the Internet.

This is The Internet Report, where we uncover what’s working and what’s breaking on the Internet—and why. Today, Kemal and I unpack an interesting BGP incident, in which a large-scale route leak briefly altered traffic patterns across the Internet. The incident began on Thursday, June 3rd at around 10:24 UTC, and resulted in a significant spike in packet loss that was noticeable in ThousandEyes tests. While this packet loss resolved within the hour (at around 10:48 UTC), we observed some interesting routing changes during this window—as traffic was diverted to a Russian telecom provider that had not previously been in the path. Watch this episode as we explore how this network provider managed to get itself into the routing paths of many major services, and why network visibility is so important to recognize these types of incidents in which your site may still be reachable but your traffic is being sent through an unexpected network.
