Getting HTTP Response 502 (Bad Gateway) when trying to access the Algorithm Lab or Documentation tabs since two-three hours back. When might this be resolved?

Related question, can I create _and_ view back tests inside Visual Studio assuming I checked out Lean? Looking for an option to avoid sitting idle twiddling my thumbs when I can't reach the site (well, it's not that bad, but you get the idea). Long term another option for me is to modify LE for my needs of course, but I'm trying to keep setup overhead to hours rather than days here.
