How do you know that? Do you know the queries William Muriithi's machine is making? Do you know what DNS servers it is querying?

I was referring to earlier days of the Internet, not his system. "The units used are seconds. An older common TTL value for DNS was 86400 seconds, which is 24 hours. A TTL value of 86400 would mean that, if a DNS record was changed on the authoritative nameserver, DNS servers around the world could still be showing the old value from their cache for up to 24 hours after the change." https://en.wikipedia.org/wiki/Time_to_live As that article mentions, with that TTL, it would take a full 24 hours for a change to be reflected.
