I just wanted to add my thanks to the Admin for getting on this. Concerning his comment about the issue being geographic, my guess is that he meant that even though the problem is likely on cryptogram.org's side of things, it may only be affecting those of us in certain geographical regions. If that's true and the Admin isn't in one of those regions, he won't be able to reproduce the issue, and it will be more difficult to pin down.
Also, I've definitely noticed short, intermittent periods of normal behavior. Someone kick the wires underneath the internet!
