This is all some Google geek's idea for a subtle TCP joke. Without getting too technical... Each packet that is transmitted via TCP has a header. Each header has certain flags containing information about the packet. SYN (synchronize) and ACK (acknowledgement) are flags. SYN followed by SYN/ACK followed by ACK is more commonly known as the "three-way handshake" (or the "TCP handshake") and you can think of it as the process by which a connection is established between two computers.
It works like this:
- The client computer sends a SYN to the server.
- The server replies with a SYN/ACK.
- The client replies in turn with an ACK.
