I thought !A meant this path is blocked by an access list.

Are you sure? Page 1163 of Cisco IOS Configuration Fundamentals states that
the character A signifies that the destination
I have always seen the !H replies when there is not a route to the
destination and when there is an access-list blocking the router then the
reply is !A using traceroute.

A---Administratively blocked (i.e. access list)
Q---Source quench
P---Protocol unreachable
N---Network unreachable
U---Port unreachable
H---Host unreachable

!H simply means that the host is unreachable. Whether this is because of an
access list or that the host is disconnected or turned off is left to the
imagination of the person receiving the !H notification. Odds are that
unless you have physical access to the host in question you will not ever
