T283027 is the main task that tracks the deployment of Wikidough as an anycasted service. One of the tasks there is, "[ ] configure the routers (Arzhel)" and in my discussions with Arzhel, we decided it's better if this is a separate task.
Configure the router side:
set protocols bgp group Anycast4 neighbor <server_IP>
Wikidough's IP is 18.104.22.168 [ see https://netbox.wikimedia.org/ipam/ip-addresses/8539/ ]. The current hosts are on codfw.
Additionally, the link above talks about:
(Optional) if deploying a new type of service, ask Netops to add a backup static route
Do you feel that this should be done for the Wikidough service?
Thank you very much for the help!
