I was excited to read the facebook hyperscale article and hitting this has sucked all the energy out of me finishing it
screenshot of article text: Dynamic DNS mapping. When a user initiates a request to facebook.com, Meta’s DNS server dynamically returns an IP address that is mapped to a Meta-operated small edge datacenter, known as point of presence (PoP), as depicted in Figure 1. This dynamic DNS mapping ensures that the chosen PoP is close to the user, while balancing load across PoPs. The user’s TCP connection is terminated at the PoP, which maintains separate, long-lived TCP connections with Meta’s datacenters. This split-TCP setup offers several advantages, including reduced TCP-establishment latency through the reuse of pre-established connections between PoPs and datacenters. A PoP typically has hundreds of servers but may have up to a few thousand. Hundreds of PoPs are positioned worldwide to ensure that most users have a PoP close to them, thereby ensuring short network latencies.
