"Server down"

[mrbk]

I was looking to test a calculation I'm doing against your result but I keep getting an error message:
"Server error: The server did not respond after 3 attempts, it may be offline."

Hi, and sorry I have not responded earlier (I think my github notifications have not been set correctly for this repo).

This is something that happens when the server goes down (unfortunately it has done that more than I'd like, and I'm looking at ways of making it more robust). Typically it will mean I have to manually go and restart the server, but it should work again whenever I do that (hopefully within the same day that it breaks).
