There was another attack going on (as you might have noticed). We're working on a fix. In the meantime, we've blocked the listing of comments, so we at least aren't down, but it did break comments.

Hope to have a fix in the next hour. Stay tuned!

Update OK we've implemented a fix, again many thanks to @sunaurus@lemm.ee for his assistance. This will prevent the outages we've seen last couple of days. Let's see what they will come up with next...
