Thanks!  But I tried that about 6 hours earlier today.  It said address had status "untested".  It also said that if I wanted my
address retested, make a TCP connection to
dns-surveyor.measurement-factory.com port 999 (e.g., with telnet) from
the address to be tested.  I did THAT also. So far, nothing.

Any other ideas?
