inetnum: -
netname: Microsoft
country: CN
descr: 6 Buildings Xigema Center No.49 Zhichun Road,Haidian District, Beijing,P.R.China

Took robots.txt and default root file then went away.

Has anyone seen this before? I see lots of log file entries, but no explanation what it does. Thanks.

I have also seen this bot. Resolves to China....MSN bot from China?
Traces to: CNCGROUP Beijing Province Network / Microsft (China) Co.Ltd

The one that hit my website, also from China and did not even ask for a robots.txt file....how rude! librabot/1.0 (+http://search.msn.com/msnbot.htm)
traces to: Data Communication Division / Beijing Telecom

Now I dont know about all you guys, but I have a long history of...shall we say "undesirable traffic" that emanates from China. Until I see a consistant "user agent" and traceable IP range for this bot, its getting blocked!

Welcome to WebmasterWorld.

What I'm seeing is Brett Yount, Moderator and Program Manager, Live Search Webmaster Tools, recommends blocking an IP Address in China. Depending on your traffic that may or may not be a good idea. All he's really saying about it is blocking that IP Address will not block msnbot. :)

"My traffic" is 65% botnet spam agents and malicious content scrapers. If Microsoft can't identify some of this new traffic then I block it and get on with my day.
