Google Captcha

[Joshua Pool via NANOG <nanog () nanog org>]

Last month one of our residential /20 blocks started to get the Captcha
page when searching Google.  Around the same time we get access denied on
QVC.com   So far nothing out of the ordinary has been observed with regards
to the networks and I do not see any blacklisting sites listing the block
in question.   I am open to any ideas and would love to have someone at
Google look into this se we can get to the bottom of this issue.

Regards,
                Josh
