Weirdness With Amazon Web Services

I added a 404 tracking database to my blogs so I can track what pages are broken. The database includes the IP address of the computer attempting to access the item. Most of the listings in the database are webpages and/or images that are broken.

But what I’ve also noticed is that there are a huge number of rows for the following item (with variations):

  • tag/web-3.0/feed/favicon.ico

When I lookup the IP address (174.129.123.x), it resolves to Amazon Web Services. I have an AWS account but have no idea why they would be trying to hit this file 100 times a day.

Anyone out there have an idea on why or how to correct the issue? Thanks in advance.
