Sqlite seems to always be too busy or temporarily unavailable and therefore never loads.
Ok, that's the point there HAS to be something wrong on your end. It has no graceful degradation issues since it's not reliant on JS, it's well under 80k for ALL eight of the files on the home page, and I've never once seen it down.
There's nothing there to even indicate it would cause problems for anyone. In terms of file-counts and sizes, it gets a massive thumbs up from me.
Or even just simple failures like a lack of max-width to make long paragraphs less of a pain the ass on larger displays.
It's a relic of the worst of transitional practices, even if it does have a HTML 5 doctype on it. Hence it wasting 8k of HTML on doing around 5k of HTML's job. Particularly bad with the "JS for nothing" on the "consortium members" section.
It's by no means a horrible site, but it does need some loving to drag it kicking and screaming into THIS century... preferably before the century is out. Oh... wait... yeah, that's probably not gonna happen.
It's very hard for me to pick a gold standard website given that 99.99% of what is out there is built on twenty year old practices and a complete ignorance of accessibility norms. The reek of ignorance amongst those building websites right now rarely to be found outside of cult-like radical extremism.
