I've never seen anything like this before, from any Internet provider. Does this mean that if I log into my Gmail and Hotmail account from Europe or Asia, that the companies do not mirror my inbox on nearby servers? What about caching?
Is Yahoo the only one that mirrors, or simply the only one to disclose it to customers?
Whatever the case, good for Yahoo for being forthcoming, and for giving users the choice.
Now, if only they'd offer their users SSL encryption for the full Webmail session (and not just the username/password), perhaps they might get a bit more regular praise from this blog.
