Browser DNS Caching: Performance Feature That Bypasses Standard DNS
We recently tested a new server management tool – it starts and stops servers. It works by updating the DNS record for the server so that when its off, users are redirected to a webpage that re-starts the server.

After quite a bit of digging we discovered that browsers cache the DNS entries to make pages load faster – and this behaviour can't easily be bypassed.
