Anycast is a routing feature BuyVM offers for free to all customers. With a functioning Anycast configuration inbound traffic will be routed to the VPS that is nearest to the visitor (i.e. European visitors will go Luxembourg, United States visitors depending on their location will go to either Las Vegas or New Jersey, Asia visitors will go to Las Vegas, etc.).
Anycast requires customer to have a VPS instance (either KVM or OpenVZ) in all three BuyVM locations (Las Vegas, New Jersey and Luxembourg).
Anycast helps speed up your sites or other services by putting visitors on server closest to them. Closest server choice results in low latency and higher throughput. It is ideal for CDN (Content Distribution Network).
Anycast is FREE for all BuyVM VPS customers. The cost will be three VPS purchases. Anycast DOES work on our popular 128MB annual plans.
Sample /etc/network/interfaces from lv-test.buyvm.net, which uses Anycast:
root # cat /etc/network/interfaces
auto lo iface lo inet loopback auto eth0 allow-hotplug eth0 iface eth0 inet static address 22.214.171.124 network 126.96.36.199 gateway 188.8.131.52 broadcast 184.108.40.206 netmask 255.255.255.0 auto eth0:v6 allow-hotplug eth0:v6 iface eth0:v6 inet6 static address 2605:6400:0020:0078::1 gateway 2605:6400:0020::1 netmask 48 auto eth0:anycast allow-hotplug eth0:anycast iface eth0:anycast inet static address 220.127.116.11 netmask 255.255.255.0
* Standard naming practice is eth0, eth0:0, eth0:1, etc. I use eth0:v6/eth0:anycast simply to identify bindings easier.
