Dear Yahoo, Please Stop DOSing me. Thanks, bye.

Yahoo is sending 3 requests a second to my webserver for no apparent reason, requesting files that do not exist, and using a HTTP/1.0 browser (WTF is up with that? Can Yahoo not access virtual hosted websites? Are you serious? Is it possible they are further behind than Microsoft?)

I realized this when trying to search my logs for an IP that a spammer used to sign up for a webhosting account with — at first I thought *he* was flooding my site with requests to prevent that information from being available to, say, figure out who he is.

The requests already violate common sense, check this out:

[Fri Sep 7 15:13:13 2007] [error] [client 209.191.87.215] File does not exist: /home/sites/sitesurvival.com/public_html/1ktnm
[Fri Sep 7 15:13:13 2007] [error] [client 209.191.87.215] File does not exist: /home/sites/sitesurvival.com/public_html/1ktnm
[Fri Sep 7 15:14:21 2007] [error] [client 209.191.87.219] File does not exist: /home/sites/sitesurvival.com/public_html/1ktnm
[Fri Sep 7 15:14:21 2007] [error] [client 209.191.87.219] File does not exist: /home/sites/sitesurvival.com/public_html/1ktnm

First off, don’t request the same URL twice in the same second. The reason this does not make sense is obvious. Second, if you receive a 404, that file does not exist. It is quite unlikely that some random jib of content was created between your first and second request (which are only separated by one minute).

Also, it’s complete rubbish to NOT IDENTIFY YOURSELF CORRECTLY AS A ROBOT:

209.191.87.219 – – [28/Nov/2007:20:19:45 -0600] “GET /nmfjopqw80gty HTTP/1.0” 404 284 “-” “Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1)”

This gives me no information as to who is constantly barraging my server with requests.

Going through the last 50,000 requests (which only reaches to about 15 hours ago) over 49,000 are requests from Yahoo for non-existent pages.
