The forum doesn't appear to have a "Site Maintenance" section. Feel free to move this topic if I missed it.
I tried to comment on one of the Blog/News pages a couple times with no success. I thought maybe it was me, so I scrolled back through several pages, and none had any comments. The new security features may be working too well to allow human comments, or not well enough to allow humans to comment, depending on how you look at it.
