Does the Internet Route Around Damage? – Baltic Sea Cable Cuts

This week's Internet cable cuts in the Baltic sea have been widely reported, even as attempts to understand their cause and impact are ongoing. We turn to RIPE Atlas to provide a preliminary analysis of these events and examine to what extent the Internet in the region is resilient to these events.

This suggest that, in the Baltic region, the Internet managed to route around the damage that occurred - for each of the physical links cut, we see relatively minor latency consequences and no visible packet loss. If this wasn't the case, we would expect our data to have looked quite different: the packet loss should have gone up; and/or the shape of the latency increases would have been gradual, as opposed to the stepwise changes we saw for the latency-affected paths. When I'm not working I like to make music (electric guitar, bass and drums), do sports (swimming, (inline) skating, bouldering, soccer), and try to be a good parent.
