Need a good website URL to test against

Question

I need a URL to just test basic http connectivity. It needs to be consistent and:

1. Always be up
2. Never change drastically due to IP or user agent. (IE: 301 Location redirect/ huge difference in content... minor would be tolerable)
3. The URL itself has a consistent content-length. (IE: it doesn't vary from by 2kb at most, ever)

A few examples, yet none match all 3 criteria:

• One example of always up: www.google.com (yet it 301 redirects based on IP location).
• Another good one is http://www.google.com/webhp?hl=en. but the problem there is that based on a given holiday, the content-length can really vary.

Answer 1

Why not go to something like http://www.google.com/ncr? Then you won't be redirected

Answer 2

You could create your own website, at least then you will know that the content will never change and you you will know when its down?

Answer 3

It might not be obvious; but http://example.com, http://example.net and http://example.org are actual, real sites; the might suit your needs.

Edit: I'm not sure about the specifics of their uptime stats and IP address, but I imagine these things, as well as the contents, are completely and utterly static.
