Well that was unpleasant!
I missed most of the down time yesterday, since my own internet was down until about 7.30pm. When I got back online, this place is down too. I checked "downforeveryoneorjustme" and it confirmed the site was down, so it wasn't just a problem at my end, plus I saw a message on the twitter page.
But I couldn't find any other info about the problem, so finally earlier today I checked on my phone and the site was fine. So I tried the DNS flush on my PC and rebooted my router...one it had rebooted though, my whole net was down again for 4 hours
Finally it's back and so is DTF
