I was just browsing successfully here today (2pm EST, 1/9/15), then gots DotDefendered.
I quit my browser (Chrome, Mac OS 10.6.8) and restarted my computer (in that order).
Once my computer and Chrome restarted, there was a delay in connecting to Bladeforums, but it's working again. Similarly, when blocked on one of my iDevices I've found that closing out Safari and trying again tends to work.
The above measures did not work for me last week, and may not going forward, but that's where things stand as of now.
