This task tracks the deployment of Wikidough as an anycasted service.
- point wikimedia-dns.org to the anycasted IPv4 and our favourite /32 (no IPv6 anycast, for now)
- add profile:🐦:anycast to Wikidough's role [🐦 -> bird!]
- update vips_filter to add Wikidough's /24
- configure the routers (Arzhel)
- deploy Wikidough as an anycasted service in at least two VMs at a given PoP to test the new setup
- update knead-wikidough tests for the new domain and IP
