Switching nameserver IP - Trouble?

[Manie]

Dear all,

I recently encountered 2 colocated customers sharing 1 IP.
Customer 1 was running ns2 on that IP, however customer 2 programmed the IP in his bios for his remote control card.

Because local presence is required to fix this we decided to switch the nameserver 2 ip.

Old situation:
ns1.rimedia.nl 195.144.2.45
ns2.rimedia.nl 195.144.2.46

Switching to
ns1.rimedia.nl 195.144.2.45
ns2.rimedia.nl 195.144.2.53

I suspect the change to take time to propangate.
I however get a strange error telling nameserver 1 is broken.

Is this normal behavior?
Cause this is still the same IP.

Thanks in advance.

oke, it has been fixed.
Seems the SOA was switched to ns2.rimedia.nl instead of ns1.rimedia.nl :S
