It looks like they sometimes have problems with the accessibility of their site. I can not reach that at times either. but that may be due to the many updates for the new page
I have never experience it each time I visit the site it actually works maybe it the timing, if they are having such issues they should try to fix it.
I think it is under maintenance or they are trying to fix an update on the site. Been trying to access the site to. We should just be patient and check back in 24 hours.
