Squid re-checks the DNS records when they expire. The default settings
of most DNS servers says that the DNS data expires in 7 days. So if the
site owner does a unplanned move to another IP address then it may take
up to a week until all clients/proxies/dns servers around the globe
notices the change.

If you build Squid with --disable-internal-dns then you can control the
expire time from squid.conf by setting the positive_dns_ttl option, and
Squid won't use the TTL setting from the DNS data.
