really? It's working for me, and I have set uptimerobot to test it and it's reporting everything ok... something weird is going on, but not sure what. Does it produce a 404 / 500 / something else?
that sounds like a webfaction error (where I host the blog), but it usually happens when the domain name doesn't match what they know they're hosting...
Are you using https anywhere or some other type of plugin that might change the URL or proxy your access somehow? (anything that might mess with the Host header somehow).
EDIT: I think I have an idea (could be the webfaction cname + IPv6 - I'll look into it...). Should work now! Sorry about that. Thanks for letting me know!
