I do agree that the website being down is annoying, but... do you think this what they want? Do you think they are going out of their way to make it take longer? No- of course not, in every single newpost Miles or Roach seem VERY annoyed when they mention the fact it still isnt up, its simply something beyond their control. Im only a, armature when it comes Web Dev/Design but seeing as before it was taken down SOME pages still worked, that implies that alot of the problems were on a individual page level, and uh.... Homestuck is very very long, so having to fix most pages INDIVIDUALLY sounds like a nightmare. And- not to be a purest or anything, but unless youre using the wiki to find page references, the Unofficial collection is just sorta objectively the best way to read Homestuck by a long shot. The website being down really isnt all that impactful at all, theres several other very accessible ways to read the comic.
I also think what you said about SAHcon is frankly really disingenuous and in bad faith, with no proof to actually back it up. Vast Error had its official license for a long while and absolutely nothing about it changed, sure maybe the team will show a couple things at the event, but acting like its just going to completely take it over is kinda ridiculous, especially consider Hiveswap (a official project) has been shown at SAHcon for years yet was only ever a very small part of it.
