These accesses of instances which are being delayed by 20 minutes - are 
they delayed for other instances in the subnet, or just for accesses 
from outside the subnet (ie through a real router)?

There may be some rather "conservative" routers out there which might 
not accept gratuitous ARPs, considering it more secure to ARP for those 
IPs explicitly itself.
