Hi Erik,

Look up "DNS pinning." I can't rule out the possibility of a faulty
DNS server but it's far more likely your customers' web browsers are
simply ignoring the DNS TTL. Malfunctioning as designed. If you keep
it live, you'll notice a falling trickle of traffic to the old address
for the next year or so.
