As Mark Twain once said, reports of my death are greatly exaggerated. 
The site is currently down due to a technical problem Basiclink (Winstep's host) has been working around the clock to solve. Unfortunately it seems that moving the site is the best solution for now, therefore the delay.
In Basiclink's defense, in the 12 years I have been working with them I never once had a problem as serious as this, any (extremely rare) downtime was usually solved in a handful of hours.
As for me having been away from Winstep in the last year, yes, it's true. It started with me needing to get away from Winstep for a while as I was burning out due to working too hard, and ended in one of the worst years of my life (which included, among other really nasty things, an accident where I broke the tibial plateau of my left leg).
Anyway, I've been working nearly non-stop on Winstep for the last 15 years (!) and we all need to get away from time to time. Brad also took a Sabbatical year from Stardock some time ago and Stardock is still here - the major difference being that Winstep is only me, so my absence is a lot more visible. 
A hiatus period similar to this happened once before and Winstep came back stronger than ever, so hold on to your pants.
