It looks like it's working here.
What browser are you using?
Is there a specific link where you're seeing the issue you're describing?
I'm getting the same as r0obear: if I go to http://reference.sitepoint.com/, it loads a blank page with the SP logo, which links back to the main SP homepage (using Opera). The page source shows the full kit and caboodle, but even turning CSS off has no effect, it doesn't render at all.
I'm using Firefox, and people I have asked to try it (all in the UK) can't access it either. So perhaps it's a locational thing?
It's working fine for me, but in my case, it defaults to this page:
It's been doing that for ages...
The devs know about it as its the same related problem as [URL="http://www.sitepoint.com/forums/showthread.php?821406-Can-t-Read-SP-Website-Articles"]http://www.sitepoint.com/forums/showthread.php?821406-Can-t-Read-SP-Website-Articles
Might take a day or so with it being weekend.
Seems to be working fine for me, but I'll flag it to the devs to look into tomorrow. Sorry for the inconvenience.
It seems to be fixed :aparty: thanks to all involved
We had some ad issues but it was just in the UK. Sorry it took so long to resolve.
