No first hand info boss. But I am sure it is a cluster of nodes. If you run SSL then the ability to scale is reduced in a big way since SSL takes a lot of CPU power. Public key crypto is very expensive as you have to decrypt the secret key using your private key for every SSL transaction. If there is no SSL then some simple DNS round robin with some other data center specific features thrown in would do nicely. I don't think anybody uses grid of server grade hardware. I doubt it. It is just good clustering. But all this is peanuts compared to Google or yahoo. Or even ebay or any other decent American website. -Girish _______________________________________________ ILUGC Mailing List: http://www.ae.iitm.ac.in/mailman/listinfo/ilugc
