Another Microsoft DoS Attack.
Yesterday morning’s Denial of Service attack was caused by Microsoft’s search bot. The offending IP was banned, this morning a new IP address started to attack the webserver with insanely rapid requests. This new IP has also been banned.
We would not ordinarily ban the ip address of web crawlers, particularly those related to a search engine. However, this MS bot is completely ignoring all of the long established rules regarding web crawling search bots and is causing significantly negative impact to warrant firewalling the server off from this malicious activity. Microsoft is launching denial of service attacks by not properly controlling their search bot’s behaviour.
