Is it really disabled or should I continue to frantically refresh ?

It's not disabled. You just have to try again. I've literally just spent 24h (well I did sleep and eat in between tries) making two withdrawals. I've seen every code 5xx page error and all sorts of 'Service disabled' and 'Tier 3 cannot withdraw' errors. It's just ridiculous. 24h for something that should take a couple of minutes.
I couldn't even get through to sell my coins due to cloudflare errors never mind make any withdrawals. I'm guessing it's going to be quite difficult to make any successful transactions until everything calms down which could be a while as there must be lots of users desperately trying to cash out continuously.
