At the network level, BGP anycast can offer unparalleled low latency performance. With our anycast technology, you can distribute your content, data, and applications to as many PoPs (points of presence) as you want, and direct incoming traffic to the nearest one. Anycast can be configured to work with nearly any application and in a wide range of use cases.
With unicast routing, users geographically further from your server will experience slower performance.
When anycast routing is used, customers experience lower latency by connecting to the server that is physically closest to them.
Anycast also ensures high availability and uptime for your infrastructure. In the event that one PoP fails, anycast architecture enables network traffic to be automatically rerouted to the next closest available PoP. In addition to server outages and failures, anycast ensures your infrastructure is not impacted if you need to take a location offline for other reasons, including upgrades, maintenance, and blue-green deployments. Anycast can also leverage ECMP and other network-level handoffs to load balance large deployments in one location.
With a unicast infrastructure, if your server goes down for any reason, users must wait until that location comes back online.
If your infrastructure is anycasted, in the event of a failure at one location, users will be seamlessly rerouted to the next closest location.
