OT: Is NovaBBS Down for Others?!

So, because of the annoying firewall they use at my (soon-to-be-ending) second job, I can't access Usenet thru ES (or using Thunderbird) when I'm there.
So I've been using NovaBBS instead, which is a web-based front end for usenet (like Google Groups used to be, before GG when bad, and then... died).
Anyway, over about the past week or two, I increasingly couldn't access RAT via NovaBBS when I tried:
https://www.novabbs.com/arts/thread.php?group=rec.arts.tv
I get a "Error: The connection to the Message Server failed." and "No article available" error messages.
And when I try other random groups they have in the "arts" listings, I usually get the same thing.
Can anyone else confirm if they are seeing the same thing when the click on the RAT link above?
(Trying to figure out if NovaBBS is really down, or if I just need to clear my cache or something... Thanks.)
