There was an odd issue with MathJax.org that provides processing for our formulas in the tests. The site was unavaialble to users in Europe and potentially other countries.... it is available in the US as we have recently checked.

We have changed the processing of the formulas ans switched it to take place locally on our server (by installing a local version of the math processing engine). It has been done about 45 mins ago and should resolve any challenges that users have had due to the DNS issue with Mathjax.org

There is a slight side effect - since we are processing formulas locally, the first time they are displayed it will take a bit more time (about one second to convert and render them). Once they have been displayed, however, they will be cached and further users will be able to see them instantly without any delay.

Please let me know if it is still not working for you.
Sorry about the issue.

Thanks bb. It's working now. Is this change going to be permanent or are you going to switch back to mathjax.org? I don't mind the 1 second delay, as least it is legible.

As far as I know, it should be permanent. It should make the experience more reliable and remove dependency on mathjax (simpler at least).
Let me know if you have any concerns or issues with that or experience. Again the first time the formulas load they will be not very snappy (will take a second) but after that they should be instantly loading.... or so I have been duped to believe :-D
