Hey, sorry about this Zac (and anyone else affected).
We brought Sucuri on to funnel traffic through and keep our server safe after someone brought us down for three hours at the start of the month trying to brute force the website. Unfortunately, it's been one string of problems after another getting set up with them (for instance... comments weren't working on the main site this weekend).
I'm probably just going to leave Sucuri turned off unless someone else brings the server down again, and then switch it on. Every time I think we've solved all the issues with them, more crop up.
