I found an increased access to my website on  www.mydomain.tld/imaginaryTeachingToolUrl.This isn't a valid URL on my site, I tried to Google this, but there are under 10 results. So I guess this specific title isn't something common - but could this be some kind of approach to hack my site?A snippet from the Apache logs. Actually this looks like a regular request. But this requests are for two reasons kind of odd:requester: from SArequest on: non English, European pagehigh number of requests (for three days now)unique ip (seems not to be a bot network or sth. like that)66.249.88.*** - - [03/May/2014:01:36:59 +0200] GET /.../style-custom.css HTTP/1.1 200 1489 http://www.google.com/imaginaryTeachingToolUrl Mozilla/5.0 (en-us) AppleWebKit/537.36 (KHTML, like Gecko; Google PP Default) Chrome/27.0.1453 Safari/537.36  66.249.88.*** - - [03/May/2014:01:36:59 +0200] GET /.../css/responsive.css HTTP/1.1 200 3584 http://www.google.com/imaginaryTeachingToolUrl Mozilla/5.0 (en-us) AppleWebKit/537.36 (KHTML, like Gecko; Google PP Default) Chrome/27.0.1453 Safari/537.36  66.249.88.*** - - [03/May/2014:01:36:59 +0200] GET /.../js/jquery.hoverIntent.js HTTP/1.1 200 470 http://www.google.com/imaginaryTeachingToolUrl Mozilla/5.0 (en-us) AppleWebKit/537.36 (KHTML, like Gecko; Google PP Default) Chrome/27.0.1453 Safari/537.36  66.249.88.*** - - [03/May/2014:01:36:59 +0200] GET /.../js/jquery.omslider.min.js HTTP/1.1 200 1008 http://www.google.com/imaginaryTeachingToolUrl Mozilla/5.0 (en-us) AppleWebKit/537.36 (KHTML, like Gecko; Google PP Default) Chrome/27.0.1453 Safari/537.36  66.249.88.*** - - [03/May/2014:01:36:59 +0200] GET /.../js/libraries.js HTTP/1.1 200 870 http://www.google.com/imaginaryTeachingToolUrl Mozilla/5.0 (en-us) AppleWebKit/537.36 (KHTML, like Gecko; Google PP Default) Chrome/27.0.1453 Safari/537.36

Okay. It appears that not all the access are here, but that does not matter. It looks like these are valid requests with an invalid referrer URL. I am not sure why since these are Google IP addresses. I looked into my abuse database and I only see valid accesses for this IP address range except for one bot trap access so I don't think you have anything to worry about. If you try and access the URL, you will get a 404. This may be a new feature/algorithm testing by Google. Congratulations! You are on the bleeding-edge of technology!
