Really? I didn't think they'd do anycast on their reverse proxy servers, that seems risky to me (ie: a TCP connection changes from one server to another due to a BGP change), but I suppose the odds are fairly low.
I seem to remember getting different IPs from different locations, but it could just be random or I could be mistaken.
EDIT: Tried now and it seems I'm getting the same IPs from Canada and Australia, so you are indeed correct.
- manigandham 10y agoYes, they have a big address space and announce all ips from every location: https://blog.cloudflare.com/cloudflares-architecture-eliminating-single-p/ https://blog.cloudflare.com/cloudflares-architecture-elimina... Pretty much all major CDNs use anycast today for load balancing, rolling downtime and security/ddos protection. Http/tcp connections are usually short-lived, relatively cheap to setup (since it's an edge network anyway) and BGP route updates don't happen that often. LinkedIn switched to anycast too after testing: https://engineering.linkedin.com/network-performance/tcp-over-ip-anycast-pipe-dream-or-reality https://engineering.linkedin.com/network-performance/tcp-ove...
