I reminded my #DistributedSystems class today that DNS is a global, decentralized, eventually consistent database with a continuous uptime and client compatibility window of 40 years, and I'm not sure that they were suitably impressed.
@geb@bortzmeyer That's fine; in class, we discussed TLDs, gTLDs, some of the drama behind ISO country codes, what happens when a domain expires or is repossessed, etc.
