I first changed the www and normal A records to a new IP, but apparently the changes were not brought up to the DNS server because the nslookup consistently returned the old info.

I then changed the NS servers of the domain to Amazon Cloud Route service, but again, it is like if nothing was commited to the DNS server and therefore the control is not given up in favour of Amazon.

Am I missing something? Should I force a commit like in some systems?

Thanks a lot, a bit desperate
