Today, I am getting an unusual error / message on checking the Google cache for any of the website through Google PageRank Toolbar. Google is saying - Our systems have detected unusual traffic from your computer network. Please try your request again later. URL for this sorry page - http://sorry.google.com/sorry/?cont...-8&q=cache%3Ahttp%3A%2F%2Fwww.google.co.in%2F
The message is generated by automated requests, using things like SEO Quake can trigger that. If you don’t use anything like that then check for viruses. Thanks Brian
It happened to me too when I used search function very frequently. Possible SEO Quake had an impact as well.
It usually shows to notify you that Google blocks the transaction like search query on Google for your IP requested too fast or multiple times for shorter time.
Usually this message appeared after frequent requests to google. The reasons can be: - seo software; - too much searches in google (up to 500 during hour or two); - some times with happens because of shared IP of your ISP (so some computers on same IP did many requests to google); - malware.
