We are seeing a large amount of server requests by IP addresses claiming to be cache.google.com and they are coming from all sorts of (unexpected) countries too. Currently the FW blocks servers that make too many connections. They are not users but it is Google trying to do something and not a human.
My question is: What are all these requests by "cache.google.com"? Why are the coming from so many different and unexpected countries? and what function am I blocking here from Google?
