Unlikely - DoS attack implies intent to take server down, and in this case this intent is not present. Does not excuse Microsoft from not having designed their crawler to avoid loops like that.

    Just a quick note of caution - if anyone’s noticing a huge increase in their bandwidth over the last month, it’s probably due to the new Microsoft search spider. We’ve had a 10x ...

      This is quite amazing. The spider must have been very active, like some trapped animal gone crazy! If all this traffic had a (considerably) negative impact on your server's perf ...

        It is a bit like a trapped animal - something extremely dangerous...  Possibly something rabid, or something with lots of bugs all over it. We're still looking into it - but the ...

          The IP address is vital - can you let us know ASAP? See the discussion here from a year ago, of some dodgy guys using the MS search bot User Agent on their bot: http://www. ...

        The Times has a cheek to compare search engines while at the same time banning any robots from their own site apart from Google! Here is so-called robots.txt that defines which ro ...
