Matt,
Thanks for your interest. The problem is resolved. The excellent Glowhost technical support folks turned us on to the gendns fix. The client can now reach the web site. We could always reach the site form our offices.
I put this in the forum simply to see if there were any other fixes to what is most likely a Google issue. Recently, a lot of folks seem to be running into this.
While I am delighted my client is satisfied, I don';t like using the gendns alternative as I lose flexibility. If I move to a new server, this site has to make individual DNS changes as we can't do a master change. When you start having exceptions problems can arise, especially since I'm old and forget things.
I really appreciate your efforts on my behalf.
