Just wondering if there is any significance to the frequency. Lately our site has been getting notably more 404 errors for alive.txt than any other uri. Is this some kind of common server log/config file, or just a fluke?
I think the "Servers Alive" product uses this. Its a monitor to make sure your site is up. Someone has a misconfigured setup somewhere.
Or there's information in that file (passwords?) that shouldn't be there and someone is just hitting all sorts of sites in the off-chance he can find one that is publicly readable.
