RH7.2 for IA64, no up2date available ?

Until in the middle of the April, I was able to make an update of
the RH7.2 for IA64 on a machine successfully by using:
	# up2date -u

After that, now I am no longer able to make update again on the u
same machine, for example:
	Script started on Mon May  5 15:40:57 2003
	# up2date -u
	Error communicating with server.  The message was:
	Error
	# exit
	exit
	Script done on Mon May  5 15:41:31 2003
What is wrong?
Has the up2date service for the RH7.2 IA64 been finished?
Do you use the rawhide for IA64 instead?
