at one point I couldn't access amazon at night.

I would get different captcha, one convoluted that wouldn't even load the required images.

And I would get the oops sorry dog page for everything.

I finally contacted amazon, gave them my (static) ip address and it was good.

In other locations, I have to solve a 6-distorted-letter captcha to log in, but that's the extent of it.
