What is the primary risk of using Anycast IP (Same IP in multiple locations) for long-lived TCP connections?

1. A It is significantly slower than unicast routing because of the multiple high-level cryptographic handshakes required to verify the identity of the global Anycast nodes.
2. B It is considered illegal in many highly-regulated jurisdictions because the non-deterministic nature of the routing violates strict data sovereignty and residency requirements.
3. C It requires a massive allocation of unique, publicly-reachable IP addresses for every single data center to ensure that the internet's routing table can be properly constructed.
4. D If a BGP route change occurs mid-connection (a 'route flap'), subsequent packets might be sent to a new server that has no record of the established state, causing a connection reset.
