Ahh hmm, I got the internal server error when I opened the link you provided but I was able to open the one that I sent. I wonder if the problem is associated with this message from above:

You have signed the CLA already but the status is still pending? Let us recheck it.

I was able to do it from home, was probably a network/security issue on my side.
