Hi Ernie thanks.
Yep I had both server sites in maintenance mode but I did not do so with 
the home sites, I wanted to see if it crashed the sites.
I too mysqldump routinely.
Problem is, because the drush up corrupted the drupal 7.12 install there 
is no way to update.php, both were dead.
My curiosity is that it had no effect on my  home setup but destroyed 
the remote server drupal set up.

Google drupal 7.12 and find the drupal.org/node/1425104 - posts dated 
2nd Feb 2012 posted by webchick  discuss the 7.12 problems. I found this 
too late.
