It looks like it's ok now. Anyway, in case of a problem you can send an email to info@ycombinator.com (assuming whatever problem they have with they webpage didn't kill also the email server).
The problem really existed and I contact them and they were able to solve the problem already, thank you
How did you write the comment?
Exactly what I was wondering. Perhaps the issue affected the `ycombinator.com` domain while leaving `news.ycombinator.com` untouched?
