You have a host registered with NSI utilizing the old IP address.

[No name] (PBOB-HST)

   Hostname: PBOB.SPEEDER.COM
   Address: 208.21.179.174
   System: ? running ?

Any query for pbob.speeder.com will not be refered to the authoritative
servers since the root servers already have the IP for pbob.

I just asked my name server and it gave the new address.

They probably still have the old NS records in their caches.  Did you tell
the old DNS provider to delete the zone from their servers?  If they still
have the zones, then every time someone queries their servers, they'll send
a new set of NS records with updated TTLs.  As long as a server queries
their server again before those TTLs run out, they'll keep getting renewed.
