I have noticed this has been down for a few days also. You might try accessing the API itself, though I find it difficult to read with my limited computer science knowledge.

PS: If anyone can figure out how to read the API so that a specific user (like myself if I logged in) can figure out how to check which exercises I still need to get light-speed badges in, I will give them a wiki-dollar!
