I have several notices that a friend request has been sent to me but when I click on the link - it says that it is not available to the moment.

Is this just me or is everyone getting the same?

there's a note on the home page about the problem.

Have the same problem, I think it's system wide.

I am getting the same thing.  I see they do now have a notice about it on the main page, that they know about it and are working on it...

Ciao!
