I tried to do a search on this but I had no luck. not sure even what keywords to use. I searched mirror, cache but I haven't found this particular situation.
I found that my ISP (UNE) located in colombia-South America, runs some sort of google server (mirror? chache?). These IP's are: 22.214.171.124 (resolves to cable190-248-34-15.une.net.co) 126.96.36.199 (resolves to cable190-248-34-13.une.net.co) and in fact if I just type those ips on my browser (or you try it in your browser) the google page is shown, even with my username logged in. If I block 188.8.131.52 youtube webpage doesn't load.
I have many questions about this.
First I want to know if is a standar procedure from ISPs outside the USA TO USE IPs THAT DOESN'T RESOLVE TO THE LOCAL GOOGLE AS CACHE SERVERS. what is weird is that the IPs doesn't resolve to something like numberhere.google.com.co
Is that a flaw in the implementation?
Such IP's don't give users trust. Any user checking that would have doubts if those IPs are legit or some one just cloning or spoofing google in some way . (I know that's not possible as the connections to these particular IPs are ssl and the certificates show no problems) But for example, I opened TCPview and saw my laptop connecting to one of those 2 IPs to port 443 and I wasn't using google at that particular moment. I saw that I had some trojan horse. but of course I don't.
Second I want to know if the way this was implemented represents a risk for the passwords and usernames somehow. Seems like perhaps the passwords security relies on how these "mirror" servers operates? idk.
Third, I wonder if because this country (Colombia) has so many issues with armed groups and narcotics trafficking , that could be just an easy way to check the info from and to google to use that for security agencies. What I find unusual is that google announced a cache server for india just this year ( not even a data center) http://trak.in/tags/business/2015/04/15/google-cache-servers-india/ and colombia is far behind them in terms of technology production or the number of the population. So its hard for me to understand why google would create a cache server (if those IPs are a cache server, I don't know how else to call them) in colombia before than in india.
Thanks for your time.
