Akamai did not work well Tuesday morning, at least for me. I do not know whether their servers
were overloaded, or couldn't get content from the source, but they did NOT work
well as seen from here.

Washington Post.com, for example, loaded ONCE for me before about 3:00 PM EDT, and I
know that site is Akamized.
