If you mean DNS, that won't work. You can lower the TTL on the zone and
get it to work better, but you ultimately cannot control what clients do.
There's also the problem that many libcurl versions shipping on Linux are
old enough to have a DNS caching bug and will hold onto the IP until
restarted.
