Microsoft bots made DDoS on CPAN
Wednesday 17 February 2010 @ 7:49 am

Bing’s (a Microsoft search engine :) ) bots made something DDoS-like on CPAN site. Why? It may be either error (“Never attribute to malice what can be easily explained by stupidity.”) or something made on purpose (for conspiracy theories fans).

Quote form CPAN Testers blog (more details):

If you’ve suffered any problems accessing any of the sites, the databases, the CPAN mirror, etc. from the CPAN Testers server last night, please direct your wrath at Microsoft. Last night the msnbot took out the CPAN Testers server with a dedicated denial of service attack. As a consequence measures are now being put in place to completely ban the msnbot from accessing at least the Reports site, and probably all the sites on the server.

Perl testers  pointed out that msnbot does not obey robots.txt file.

    The bots are still attacking the site for around 10 minutes every hour. Around 40-50 different IPs, though their rate is down to roughly 1 requests every few seconds. Enough to still be a nuisance. They are still banned and until I see much better co-ordinated requests that ban will remain in place.

    So much for the apology from the Bing developer.
