In simple terms, Border Gateway Protocol (BGP) is the protocol that routes traffic on the Internet. During last week’s attack, the attacker was redirecting traffic that belonged to Amazon’s Route 53 DNS servers.

The CDN and the ISP peers over an IXP, the volume drives port upgrades, and private connections are impossible. Removing traffic from the edge will save money on transit and IXP port fees and lower the risk of congestion. There are more efficient ways of operating DNS resolvers, so are there any workarounds available?

Take the example of one service needing to lookup the execution address for an API gateway hosted by another service. DNS is another great example of this. Think of it like the USB-C port for your system. We need everyone to plug into the same adapter interface but can offer a wide variety of experiences through that USB-C port!

Bad hardware (the switch or router port). Packet capture : By strategically locating one or more probes off of mirrored ports on the network, sessions can be monitored, but if the loss occurred in the cloud, we will have no idea where it occurred. To learn more, read “ How to Monitor Traffic Through Transit Gateways.”.
